Question 18:

If 0.750 mole of nitrogen gas occupies a volume of 23.1 L at zero Celsius, what volume will 3.50 mole of nitrogen gas occupy at the same temperature and pressure?

Answer 1

Constant temperature and pressure:

V1/n1 = V2/n2

Volume is related to moles

23.1 L/0.750 mol = V2 / 3.50 mols

V2 = 107.8 L

The number of moles increased from 0.750 to 3.50, which is 4.666 x

4.666 x the original volume of 23.1 L = 107.8 L
