Chapter 1, Problem 1.39NP

Interpretation Introduction

Interpretation:The molar density at the pressure of $\text{1}\text{.0 }\times {\text{ 10}}^{\text{-10}}\text{ torr}$ in a vacuum chamber at 300 K needs to be determined. The fraction of molecules in gas phase present for 1.0 atm in the chamber at $\text{1}\text{.0 }\times {\text{ 10}}^{\text{-10}}\text{ torr}$ needs to be determined.

Concept Introduction: The ideal gas equation is the equation which gives the relations between P,V, n and T of gases. It can be written as:

  $PV=nRT$

Here, P is pressure, V is volume, n is number of moles, R is Universal gas constant and T is temperature.
