Chapter 10, Problem 9PE

Interpretation Introduction

Interpretation:

The volume, in liters, of oxygen gas that is consumed by methane during the combustion process is to be calculated.

Concept Introduction:

Avogadro’s law helps in explaining the relationship between the volume and the number of moles in an ideal gas which is at constant temperature and pressure.

The law states that the number of moles present in gas is directly proportional to the volume of the gas, provided that the temperature and the pressure of the gas are not altered.

The relationship expressed in Avogadro’s law, regarding the number of moles and the volume of gas at constant pressure and volume, is expressed as:

$V\alpha n$

Here, $V$ is the volume of gas, $n$ is the number of moles present in the gas, and the expression shows the direct proportionality between the volume and the number of moles of the gas.
