Question

How many moles of Fe are produced from 7 moles of Zn?
Zn(s) + FeSO4(aq) → ZnSO4(aq) + Fe(s)

Answer 1

7 mol Fe

General Formulas and Concepts:

Chemistry

• Stoichiometry

Step-by-step explanation:

Step 1: Define

RxN: Zn (s) + FeSO₄ (aq) → ZnSO₄ (aq) + Fe (s)

Given: 7 moles Zn

Step 2: Stoichiometry

`7 \ mol \ Zn((1 \ mol \ Fe)/(1 \ mol \ Zn) )` = 7 mol Fe

Step 3: Check

We are given 1 sig fig.

Since our final answer is in 1 sig fig, there is no need to round.
