5.16 Molar volume

Question 1

Molar volume

Answer 1

Equal amounts in moles of gases occupy the same volume under the same conditions of temperature and pressure

1 mole of gas at room temperature is 24 dm3

Volume (dm3) of gas at room temp = Mol x 24
Volume (cm3) of gas at room temp = Mol x 24,000

Question 2

Calculating the volume of gas

Answer 2

Volume = molar volume x amount
For example if you had 6 moles of O2, at room temp you would have a volume of 6 x 24 = 144 dm3 of O2
