Chapter 6, Problem 102IAE

Interpretation Introduction

Interpretation:

The mass percent of helium in the mixture should be calculated.

Concept introduction:

The ideal gas equation for gases gives the relation of P, V, T and number of moles of gases. It is also related to the density of gas with the given mathematical expression:

$\begin{array}{l}\text{P }\times \text{ V = n }\times \text{ R }\times \text{ T }\\ \text{P }\times \text{ V = }\frac{\text{Mass}}{\text{Molar mass}}\times \text{ R }\times \text{ T }\\ \text{P }\times \text{ Molar mass = }\frac{\text{Mass}}{\text{V}}\times \text{ R }\times \text{ T }\\ \text{P }\times \text{ Molar mass = d }\times \text{ R }\times \text{ T }\end{array}$
