Chapter 3, Problem 95AE

Interpretation Introduction

Interpretation: The elements $\text{M}$ and $\text{X}$ are to be identified in the compound ${\text{MX}}_{\text{3}}$ . The correct name of the compound ${\text{MX}}_{\text{3}}$ is to be stated. The mass of ${\text{MX}}_{\text{3}}$ prepared from $1.0g$ each of $\text{M}$ and $\text{X}$ is to be calculated.

Concept introduction: The mass percentage is used as one of the ways to estimate the composition of a compound. It expressed in terms of percentage by mass of elements that constitute that compound. The formula for mass percent involves the ratio of element’s mass in one mole of compound to molar mass of compound. The final value of mass percent is obtained by multiplying this ratio with $100$ .
