Chapter 7, Problem 70APP

(a)

Interpretation Introduction

Interpretation : Calculate the mass percent composition for each of element given with the help of their masses.

Concept Introduction : Mass percent composition can be given as:

  $\text{Mass percent of element =}\frac{\text{Mass of the element}}{\text{Molar mass of element}}\text{ x 100}$

It can be written as:

  $\text{Mass percent of element =}\frac{\text{Mass of the element}}{\text{total mass }}\text{ x 100}$
