if 40.0 g of methane gas reacts with 40.0 g of oxygen gas whis it the limiting reactant
1. Write and balance the equation.
2a. mols O2 = grams/molar mass
2b. mols CH4 = grams/molar mass.
3a. Convert mols O2 to mols of a product.
3b. Do the same for mols CH4.
3c. The limiting reagent in these problems is ALWAYS the reagent that provides the FEWER mols product.
