Chapter 8, Problem 19E

Interpretation Introduction

(a)

Interpretation:

The number of particles in $\text{1}\text{.50}\text{g}$ potassium $\text{K}$ 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 $\text{6}{\text{.022×10}}^{\text{23}}$ atoms.

Interpretation Introduction

(b)

Interpretation:

The number of particles in $\text{0}\text{.470}\text{g}$ oxygen ${\text{O}}_{\text{2}}$ is to be calculated.
