Hydrogen gas, H2, reacts with nitrogen gas, N2, to form ammonia gas, NH3, according to the equation


3H2(g)+N2(g)→2NH3(g)

AHow many moles of NH3 can be produced from 18.0 mol of H2 and excess N2?

BHow many grams of NH3 can be produced from 3.46 mol of N2 and excess H2.

CHow many grams of H2 are needed to produce 13.36 g of NH3?

DHow many molecules (not moles) of NH3 are produced from 1.49×10−4 g of H2?
