Chapter 6, Problem 6.95SP

Interpretation Introduction

Interpretation:

The identity of metal $\text{M}$ in a certain metal sulphide with formula ${\text{MS}}_{\text{2}}$ has to be identified.

Concept Introduction:

Molecular weight:

Molecular weight is the mass of the molecule, which is calculated as the sum of the atomic weights each constituent element in the molecule multiplied by the number of atoms of that element has in the molecular formula.

Percentage of $\text{S}$=$\frac{\text{atomic}\text{mass}\text{of}\text{S}}{\text{X}}$

Atomic mass of Metal in ${\text{MS}}_{\text{2}}$= $\text{molecular}\text{mass}\text{of}{\text{MS}}_{\text{2}}\text{-2(sulphur}\text{atomic}\text{mass)}$
