Chapter 5, Problem 181IP

Interpretation Introduction

Interpretation: The identities of M and X are to be identified. The correct name of ${\text{MX}}_{\text{3}}$ is to be stated. Also, the mass of ${\text{MX}}_{\text{3}}$ is to be calculated.

Concept introduction: The molecular formula of an element defines the total number of atoms present in a molecule. The number of moles is defined as the ratio of mass with the molecular mass of an element. The mass of an element is the amount of the substance present in an element. The mass is calculated by using number of moles in an element.

To determine: The identities M and X, the correct name of ${\text{MX}}_{\text{3}}$ and the mass of ${\text{MX}}_{\text{3}}$.
