Chapter 3, Problem 3.122MP

Interpretation Introduction

(a)

Interpretation:

The atomic weight and identity of halogen X needs to be determined.

Concept introduction:

Atomic weight is a relative atomic mass and also the ratio of the average mass of a Chemical element of atoms to some standard.

The number of moles can be calculated from mass and molar mass as follows:

$\text{n=}\frac{\text{m}}{\text{M}}$

Here, m is mass and

M is molar mass.

Interpretation Introduction

(b)

Interpretation:

The atomic weight and identity of Metal $\text{M}$ needs to be determined.

Concept introduction:

Atomic weight is a relative atomic mass and also the ratio of the average mass of a Chemical element of atoms to some standard.
