Chapter 6, Problem 6.51QE

Interpretation Introduction

Interpretation:

The molar mass of a $0.121\text{ g}$ gas at $29°\text{C}$ that occupies $21\text{ mL}$ volume and has a pressure of $740\text{ torr}$ has to be calculated.

Concept Introduction:

Any gas obeys the assumption laid down in kinetic molecular theory is said to be an ideal gas. The combination of all the gas laws namely Boyle’s law, Charles law and Avogadro’s leads to the ideal gas equation that can be used to relate all the four properties such as given below:

  $PV=nRT$        (1)

Here,

$\text{R}$ is the universal gas constant.

$V$ denotes the volume.

$n$ denotes the number of moles.

$T$ denotes temperature.

$P$ denotes the pressure.
