Chapter 5, Problem 5.141P

Interpretation Introduction

Interpretation:

The average molar mass of dry gas at $\text{10 }°\text{C}$ and $\text{102}\text{.5 kPa}$ is to be calculated.

Concept introduction:

The expression to calculate the density of a gas is as follows:

$d=\frac{PM}{RT}$ (1)

Here, $d$ is the density, $P$ is the pressure, $M$ is the molar mass, $T$ is the temperature, $R$ is the gas constant.

The ideal gas equation can be expressed as follows,

$PV=nRT$

Here, $P$ is the pressure, $V$ is the volume, $T$ is the temperature, $n$ is the mole of the gas and $R$ is the gas constant.
