Chapter 8, Problem 8.107CP

(a)

Interpretation Introduction

Interpretation:

The molecular weight of the methane gas and its density in gram per litre should be identified.

Concept introduction:

Ideal gas law: The gas law which relates the variables temperature, volume, pressure and the number of molecules and this law can be mathematically expressed as:

$\text{PV}\text{=}\text{nRT}$

It can also be defined as that one mole of any gas contains a volume of $\text{22}\text{.4}\text{L}$ at $\text{0°C}\text{and}\text{1}\text{atm}\text{pressure}$.

The conditions of $\text{0°C}\text{and}\text{1}\text{atm}\text{pressure}$ is called as standard temperature and pressure $\left(\text{STP}\right)$

$\text{Density}\text{=}\frac{\text{mass}}{\text{volume}}$
