Acrylonitrile (c3H3N ) is the starting material for many synthetic carpets and fabrics. It is produced by the?
following reaction:
2C3H6 (g) + 2NH3 (g) + 3O2 (G0 - 2C3H3N (g) + 6H2O (g)
If 15.0 g C3H6, 10.0 g 02, and 5.00 g Nh3 are reacted, what mass of the acrylonitrile can be produced assuming 100% yield?
----------I found the moles of c3h3n which is 56 .i do not know what to do next?

If you have mols acrylonitrile you have what you want don't you? grams = mols x molar mass. However, you don't show any work and I can't know that you did it right. Here is the way to solve the problem.
mols C3H6 = grams/molar mass.
mols NH3 = grams/molar mass.
mols O2 = grams/molar mass.

I have no idea what(G0 - 2C3H3N) means. I hope that somehow stands for an arrow but you could have written ==> a lot easier.

Now use the coefficients in the balanced equation to convert mols C3H6 to mols of the product.
Do the same for mols NH3 to mols product.
Do the same for mols O2 to mols product.

It is quite likely that the three numbers will not be the be same because this is a limiting reagent problem which means two of the values are not right. In limiting reagent problems the correct value is ALWAYS the smallest one and the reagent providing that value is the limiting reagent. Then grams of product = mols x molar mass product.
