Chapter SM, Problem 12PQ

Interpretation Introduction

Interpretation:

The molar mass of ideal gas that occupies volume of $300\text{ mL}$ at $35°\text{C}$ and $789\text{ mm Hg}$ has to be determined.

Concept Introduction:

The ideal gas equation is used to predict behavior and properties of various gases under certain conditions. It represents relationship between pressure, temperature, volume and amount of gas.

The formula for ideal gas equation is as follows:

  $\text{PV}=\text{nRT}$        (1)

Here,

  $\text{P}$ is pressure of gas.

  $\text{V}$ is volume of gas.

  $\text{T}$ is temperature of the gas.

  $\text{n}$ is number of moles of gas.

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