Chapter 2, Problem 87IAE

Interpretation Introduction

Interpretation:

The volume of unreacted zinc needs to be calculated.

Concept introduction:

The number of moles can be calculated from mass and molar mass as follows:

$n=\frac{m}{M}$

Here, m is mass and M is molar mass.

The density of a substance is related to mass and volume as follows:

$d=\frac{m}{V}$

Here, m is mass and V is volume.
