Chapter 10.7, Problem 1CYU

Interpretation Introduction

Interpretation:

Molar mass of the unknown gas has to be calculated from the given data.

Concept Introduction:

Effusion: Movement of gas through tiny pore in a container into another having low pressure.

Comparing rate of effusion of two gases:

  $\frac{\text{Rate}\text{of}\text{effusion}\text{of}\text{gas}\text{1}}{\text{Rate}\text{of}\text{effusion}\text{of}\text{gas}\text{2}}\text{=}\sqrt{\frac{\text{molar}\text{mass}\text{of}\text{gas}\text{2}}{\text{molar}\text{mass}\text{of}\text{gas}\text{1}}}$

The amount of gas moving from one place to another and square root of its molar mass are inversely proportional.
