Chapter 2, Problem 66E

Interpretation Introduction

Interpretation:

The sample which occupies the largest volume needs to be identified from the given options.

Concept introduction:

1. A mole is an SI unit of measurement which relates the amount or mass of a substance to the number of particles present in it.
2. The relationship between moles and the number of particles is expressed via the Avogadro constant:

$\begin{array}{l}1\text{ mole = 6}\text{.023}\times {\text{10}}^{23}\text{ atoms (or any particle)}\\ \text{where mole = }\frac{\text{mass of the substance}}{\text{molar mass}}\end{array}$

3. Greater the number of moles of the substance, the greater will be volume occupied.
