Chapter 2, Problem 2.33P

Interpretation Introduction

(a)

Interpretation:

Number of moles of ${\text{H}}_{\text{2}}\text{O}$ is to be calculated.

Concept introduction:

The expression to calculate number of moles is as follows:

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

Rearrange above equation to calculate mass as follows:

$\text{Mass}\left(\text{g}\right)=\left(\text{Number of moles}\right)\left(\text{Molar mass}\right)$

Interpretation Introduction

(b)

Interpretation:

Number of deuterium atoms is to be calculated.

Concept introduction:

The expression to calculate number of moles is as follows:

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