a mass of 80 grams of hydrogen gas is heated with nitrogen gas to produce ammonia gas .what is the mass of ammonia that will be produced

1 answer

H2 is 2 grams/mol
so we have 40 mols of H2 which is 80 mols of H

for each mol of H we get 1/3 mol of NH3
so we get 80/3 mols of NH3

NH3 is 14+3 = 17 grams/mol

(80/3)mols * 17 grams/mol = 453 grams NH3
