Chapter 12, Problem 12.92QP

Interpretation Introduction

Interpretation:

Mole fraction of Oxygen, Nitrogen and Helium in a sample are given, their respective mass in the sample has to be calculated.

Concept Introduction:

A mixture is at least made up of two components.  Mole fraction of a component in the solution correlates to the ratio of number of moles of that component to the total number of moles.  It is expressed as,

$\text{Mole fraction = }\frac{number\text{ of moles of a component}}{total\text{ number of moles in the solution}}$
