SOURCE: mcculloch 310 oil mix ratio

The proper gas/oil ratio is 50:1, that is 50 parts gas, to one part (2) cycle oil.

If you plan on leaving gas in the tank when not being used, I always recommend adding some gas stabilizer, such as Sta-bil, which makes starting the chain saw easier regardless of how long the fuel mix has been sitting in the tank or saw (up to 2 years according to Sta-bil label)

Hope you find this Very Helpful and best regards!

On the container of 2 cycle oil you buy, it will have a mixing chart. 50:1 (means 50 parts of gas to 1 part of oil) usually uses around 4 ounces of 2 cycle oil to each gallon of gasoline. The other compartment is for bar & chain oil, that is what lubricates the bar & chain.

Fuelleaking from the cap will not stop it running, 40-1 with good quaility two stroke oil shoule be fine, if there is a good spark and fuel at the plug, you need to check that the piston has not picked up, the hottest part of the engine is the exhaust side, so remove the muffler, and take a look at the piston skirt throught the open exhaust port, any signs of scuffing and it will need to come apart to check the damage.

How do I figure 10% of any given amount of liquid?


3 oz is 88 mL of paint
10 percent is 8.8 ml
Can you get a syringe from the chemist then you can suck up the hardener into it to 8.8 ml
it is about 1/2 a teaspoon
or 8.8 cc

I need to convert 300 grams of mascarpone italian cheese into something i can understand


Don't forget cups are measurements of volume not weight. It was so the old west cowboys could cook using their tin mug as a measure. The problem with converting weight to volume is as follows, a cup of sugar is heavier than a cup of flour. Whole almonds have air spaces between them. This site is a flour site, but lower down, cups of various ingredients by weight. With the two sites listed, you can convert everything. Good luck, I am a trade chef.
http://www.kingarthurflour.com/learn/ingredient-weight-chart.html

300 grams is 10 1/2 ounces

200 grams is 7 ounces

This calculator site will convert everything including grams to ounces and using the 'VOLUME' tab, grams to cups.

Bubbles after 24 hour cure


I recently covered a wooden chair in epoxy resin. It is the nature of the product to create bubbles as it hardens. The directions stated to gently blow on the bubbles as they formed. Check it often and blow on any bubbles that form in the first 45 minutes after application. This worked quite well for me. Be sure to wipe up any drips in that first 45 minutes too, they are a pain to sand when they are dry!

The instructions in the Attwood Vinyl and Leather Repair Kit call for using Clear Vinyl Adhesive and Filler. Is the Filler the same thing as the Powder Hardener. If not, what is the hardener for? If it...


The hardener is for use when you have "hard" vinyl, like on the dash or in a door panel. Do NOT use this where the vinyl needs to remain very flexible, such as on a seat. I believe, though I am not sure, that you add about 20 of the hardnener to your color mix goop if you decide to use it. This should definitely be in the instrucitons. No idea why its not there.

Clculate the amount of oxygen for the combusion of carbon 188gms calculate the mass of carbondioxied form?


This problem is the type often encountered in a first semester chemistry course, whether in high school or college.

It is very easy to solve if you already understand the following concepts, and if you also have had lots of practice applying them!
  • PROPORTIONS
  • THE MOLE
  • The LAW OF CONSERVATION
  • CHEMICAL EQUATIONS
  • BALANCED CHEMICAL EQUATIONS
  • STOICHIOMETRIC CALCULATIONS
  • SIGNIFICANT FIGURES, PRECISION, & ROUNDING OFF CALCULATED QUANTITIES
Initially, I will assume you already understand the above concepts, except for "stoichiometric calculations." I'd be happy to focus more on the other topics at another time, depending on interest, as indicated by posted questions.

To solve this problem you must be aware of the balanced chemical equation, as follows:
dubblea.jpg Notice that there is one C, one O2, and one CO2.
(For convenience in my post, I am writing the subscripts on the same line,)

"One what?" You might ask. It can be one "molecule" for each the O2 and CO2; and one "atom" of C. For the method of stoichiometry in this problem, we should use one "mole." So, there is one mole of C, one mole of O2, and one mole of CO2. In other words, the PROPORTION of these reactants (C and O2) and product (CO2), is one to one to one, also written one:one:one (or 1:1:1).

As I am assuming you know, these numbers are called the "coefficients" of the balanced chemical equation.

To calculate the mass in grams of O2 (the unknown quantity), we will need only the moles of O2 and the moles of one other substance from the balanced chemical equation. Since we are given the mass of C, we can use the moles of C.

TO WORK A STOICHIOMETRIC problem using a balanced chemical equation, YOU MUST INCLUDE THE MOLES OF TWO SUBSTANCES from the chemical equation in your calcuation, in this case, moles of C and moles of O2. As you know, you can calculate moles of C from the mass (in grams) of C that was given in this problem. You must calculate the moles of O2 by use of the following math expression:

mol O2 = (MOLE RATIO of O2 to C) x mol C.

(Notice that I have used the official abbreviation of moles, which is "mol".)

I will show you how to calculate the MOLE RATIO a moment.

Once you have caculated the moles of O2, you will have only one more calculation to do to calculate the number of grams of O2. Since I am assuming you already know how to calculate grams from moles, I will skip this step until my closing summary.

The MOLE RATIO can be calculated as follows:dubblea_2.jpg The calculated mole ratio will always equal the ratio of corresponding coefficients.

Notice that the mole ratio actually represents the ratio of the coefficients that are in the balanced chemical equation, and is written in the same order as are the calculated (calc'd) moles.

Therefore,
dubblea_4.jpg
So, you can see that the number of moles of O2 = calculated moles of C.

The moles of C were calculated as follows:

The calculated moles of C = [grams C] / [MW of C] = [188 g C / 12.0 g] = 15.7 mol C


Therefore, there are 15.7 moles of O2, as calculated from use of the math expression (with boxes) shown above.


The wanted GRAMS of O2 are calculated from MW of O2 times its number of moles, as follows:


Grams of O2 = 32.0 g O2 x 15.7 mol O2 = 502 grams O2.



For your convenience as you make conversions among grams and moles, you may use the following memory aid: dubblea_5.jpg

To go from moles to grams, just notice that moles are beside MW, so multiplying them will give grams (moles x MW = grams). If you want to go from grams to moles, notice that grams are over MW, so (grams/MW) = moles. If you should want to calculate MW, you would divide grams by moles, (grams/moles) = MW.


One more tip: When doing calculations, use at least the same number of significant figures (sig figs) in the molecular weights (and atomic weights) as is in the given numerical data. That is, since there are three sig figs in 188 grams of C, use 12.0 as the atomic weight of C, and 44.0 as the MW of CO2. You would obtain the same answer using 12 and 44, but as you may know, following this rule would be more important in other problems in which the digit past the decimal is not zero. This allows proper rounding off of the final calculated quantity.


In Summary

  • Write the chemical equation, and balance it.
  • Use MOLES to do the necessary stoichiometric calculations. Convert grams to moles to make this possible.
  • Multiply the calculated moles of the given amount of chemical compound (or element) by the COEFFICIENT RATIO of the two compounds involved in the problem.
  • Convert moles to grams if grams are asked for by the problem.
  • Round off correctly.
  • Show the answer quantity, which should always show both numerical value AND unit.

Suggestion: Try out this method to other problems involving a chemical reaction. Good luck!

How much resin and hardener should i mix up, i'm building a fairly big subwoofer enclosure and i'm not sure how big of a batch to make....... this is my first fiber glass enclosure, but i want to get it...


fist you need to find out how much air space you need for each speaker thats going in the box then you will need a frame something light but durable you can get sound board from lowes thats wat you need to start with and when your mixing your hardener and fiber glass mix only a small amount at a time just a little hardener add to much and it will dry immediatly if you mix a lot of it at once you will waste most of it do it during the day it needs to be around 60 degrees to get it right

How to repair tent trailer roof


Go to an auto parts store and buy a fiberglass kit. Resin, hardener and cloth. Clean and rough the area. apply a coating of mixed resin, then a layer of cloth. Let it dry and repeat a couple of times. After you are satisfied with that get a gallon of Elastomeric, you will find it at Lowes/Home depot. Clean the entire top and apply 2 coats with a brush or roller about 24 hours apart. No rain or moisture for a couple of days. Project complete, water proof roof.
