How many moles of H₂ are needed to produce 9.33 moles NH₃?
Balanced equation:
N₂ + 3 H₂ ⟶ 2 NH₃
Theoretical number of moles of H₂ needed to produce 9.33 moles NH₃ :
(9.33 moles NH₃) * (3 moles H₂ / 2 moles NH₃) = 14.0 moles H₂

What mass in g of copper is produced when 3.8 g of Fe is reacted with excess CuSO₄ ?
Fe + CuSO₄ ⟶ Cu + FeSO₄
Theoretical yield in grams of Cu from 3.8 g Fe :
(3.8 g Fe) * (1 mole Fe / 55.85 g Fe) * (1 mole Fe / 1 mole Cu) *
(63.55 g Cu / 1 mole Cu)
= 4.3 g Cu
