Question

i) What is meant by molar volume of a gas?​

Answer 1

Explanation:

Molar gas volume

At a given temperature and pressure, one mole of any gas occupies the same volume.

The molar volume is the volume occupied by one mole of any gas, at room temperature and pressure.

The molar volume is equal to 24 dm3 (24,000 cm3). This volume is given in questions that need it.

A molar cube of 29 cm dimensions

A cube with 29 cm sides has a volume of just over 24 cubic decimetres

Using the molar volume

Calculating the volume of a gas

The volume of a known amount of gas can be calculated:

Volume = amount in mol × molar volume

Answer 2

The molar volume is the volume occupied by one mole of any gas, at room temperature and pressure. The molar volume is equal to 24 dm 3 (24,000 cm 3). This volume is given in questions that need it.
