4NH3 (g) + 5O2 (g) → 4NO (g) + 6H2O (l)
(a) How many moles of nitric oxide (NO) can be produced if 0.523 moles of NH3 were used and oxygen gas is in excess?
(b) What is the theoretical mass of NO if 0.523 moles of NH3 were used and oxygen gas is in excess?
(c) What is the percent yield of the reaction if the actual yield of NO was 6.625 g?
