Question 41

The volume of a gas at room temperature and pressure (rtp) can be calculated using the equation:

volume in $dm3\text{dm}^3$ = amount in $mol×24\text{mol} \times 24$

Rearrange the equation to give the amount, in moles, of a gas.

[1]

A sample of nitrogen has a volume of 3.6 dm³ at rtp.

Calculate the amount, in moles, of nitrogen in the sample.

[1]

The relative formula mass of nitrogen, $N2\text{N}_2$ , is 28.

Calculate the mass of nitrogen in the sample.
