Chapter 2, Problem 55E

Interpretation Introduction

(a)

Interpretation:

The total number of atoms in the given species needs to be calculated.

Concept introduction:

According to Avogadro’s law, in 1 mol of a substance there are $6.023\times {10}^{23}$ atoms. Thus, from number of moles and Avogadro’s number, the number of atoms of an element can be calculated as follows:

$N=n\times N_A^{}$

Here, n is number of moles and $N_A^{}$ is Avogadro’s number with a constant value of $6.023\times {10}^{23}$.
