Question 30

Two gas samples are at the same temperature and pressure.

Sample	Amount of gas (mol)	Volume of gas (dm³)
X	0.30	7.2
Y	—	9.6

Calculate the amount of gas in sample Y.

[1]

Sample X is nitrogen and sample Y is carbon dioxide.

A student says that sample Y has the greater volume because carbon dioxide molecules are larger than nitrogen molecules.

Explain why the student is wrong.
