This is a limiting reagent (LR) problem. You know that because amounts are given for BOTH reactants. Here is a step by step procedure for working LR problems. Print this procedure out.
1. Write and balance the equation.
CH4 + 2O2 ==> CO2+ 2H2O
2. Convert what you have to mols.
mols CH4 = grams/molar mass = ?
mols O2 = grams/molar mass = ?
3a. Using the coefficients in the balanced equation, convert mols CH4 to mols of either product.
b. Do the same and convert mols O2 to mols of the same product.
c. It is likely that these two values will not be the same which means one of them is not right. The correct value in LR problems is ALWAYS the smaller value.
4. Now convert the smaller number of mols of the product to grams. g = mols x molar mass
When 85g of CH4 are mixed with 160g of O2 what is the maximum amount of CO2 that can be produced?
