Sample Problem 3.10
Calculating Amounts of Reactant and Product in Reactions Involving a Limiting Reactant
PROBLEM:
A fuel mixture used in the early days of rocketry was composed of two liquids, hydrazine (N2H4) and dinitrogen tetraoxide (N2O4), which ignite on contact to form nitrogen gas and water vapor. How many grams of nitrogen gas (N2) form when 1.00 x 102 g of
PLAN:
Start with a balanced chemical equation and find the number of moles of reactants; identify limiting reagent; determine grams of N2 formed.
mol of N2
mol of N2
divide by M
molar ratio
