Chapter 8, Problem 3E

Interpretation Introduction

(a)

Interpretation:

The mass of $6.02\times {10}^{23}$ atoms of sodium is to be calculated.

Concept introduction:

One mole of atoms, molecules or particles is defined as a quantity whose mass is equivalent to its gram atomic mass or molecular mass. One mole of any substance possesses fixed Avogadro’s number, which is equivalent to $\text{6}{\text{.02×10}}^{\text{23}}$ atoms.
