The volume of the gas is 
Explanation:
At standard temperature and pressure (stp), the volume occupied by 1 mole of an ideal gas is always equal to

In this problem, we have an amount of moles of gas of
n = 0.034 mol
Since 1 mol of gas occupies a volume of 22.4 L, we can set up the following ratio:

where V is the volume occupied by 0.034 mol of gas. Solving for V, we find

Or, in cubic metres,
