Chapter 20, Problem 95CWP

(a)

Interpretation Introduction

Interpretation: The percent volume fraction of xenon, atmospheric pressure and temperature and dimensions of the room are given. The mass of the xenon in the room is to be determined. Also the number of xenon atoms inhaled in the given volume of air is to be calculated.

Concept introduction: The ideal gas equation is given as,

$\text{Pressure}\times \text{Volume}=\text{Number}\text{of}\text{moles}\times \text{Gas}\text{constant}\times \text{Absolute}\text{temperature}$

One mole of a substance is equivalent to $22.4{\text{dm}}^{\text{3}}$.

To determine: The mass of xenon in the room of the given dimension.
