Question

How many grams of N2 can be produced when 7.60 g of O2 reacts

Answer 1

with excess NH3

7.60 g of O2 reacts with 2 mol of NH3 to produce 2 mol of N2 and 4 mol of H2O.

Molar mass of N2 = 28.02 g/mol

Therefore, 2 mol of N2 weigh 56.04 g.

Therefore, 7.60 g of O2 reacts with excess NH3 to produce 56.04 g of N2.
