According to this chemical reaction, which is the number of grams of Fe produced from 14 moles of H2? Fe3O4 + 4 H2 → 3 Fe + 4 H2

IRINA_888 [86]

Answer:

$\boxed{\text{586 g}}$

Explanation:

We know we will need a balanced equation with masses, moles, and molar masses, so let’s gather all the information in one place.

M_r: 55.85

Fe₃O₄ + 4H₂ → 3Fe + 4H₂O

n/mol: 14

1. Use the molar ratio of Fe:H₂ to calculate the moles of Fe.

$\text{Moles of Fe = 14 mol H$_{2}$} \times \dfrac{\text{3 mol Fe}}{\text{4 mol H$_{2}$}} =\text{10.5 mol Fe}$

2. Use the molar mass of Fe to calculate the mass of Fe

$\text{Mass of Fe = 10.5 mol Fe} \times \dfrac{\text{55.85 g Fe}}{\text{1 mol Fe}} = \textbf{586 g Fe}\\\\\text{The reaction will produce $\boxed{\textbf{586 g}}$ of Fe}$
