Chapter 4, Problem 27E

Interpretation Introduction

Interpretation:

The mass of hydrogen gas produced should be calculated.

Concept introduction:

The study in which the amount of materials i.e. reactant or products are consumed or produced is known as stoichiometry.

Number of moles is defined as the ratio of mass to the molar mass. The mathematical expression is given by:

Number of moles = $\frac{\text{ mass}}{\text{Molar mass}}$

The mathematical expression for density is:

$\text{density=}\frac{\text{mass}}{\text{volume}}$
