Chapter 3, Problem 94E

Interpretation Introduction

Interpretation:

The given question stated that a metal $\left(\text{M}\right)$ forms an oxide with the formula $\left({\text{M}}_2\text{O}\right)$ . If the oxide contains $16.99\%\text{O}$ by mass, then the metal is to be identified.

Concept introduction: The formula to calculate formula mass is,
   $\text{Formula}\text{mass}=\left({\text{N}}_{\text{1}}\times {\text{x}}_{\text{1}}\right)+\left({\text{N}}_{\text{2}}\times {\text{x}}_{\text{2}}\right)+\mathrm{...}+\left({\text{N}}_{\text{n}}\times {\text{x}}_{\text{n}}\right)$

The mass percent composition for each element is calculated by the formula,
   $\text{\%}\text{Mass}=\frac{{\text{M}}_{\text{1}}}{{\text{M}}_{\text{w}}}\times 100$

To determine: The name of metal present in given formula $\left({\text{M}}_2\text{O}\right)$ .
