By applying ideal gas equation,
[tex]P\times V=n\times R\times T[\tex]
Where, P= pressure of gas
V=volume of gas
R=Gas constant
n=Number of moles of gas
T=Temperature
At STP, each gas has a defined value of pressure, volume and temperature.
P= 1 atm
R=0.0821 L atm mol⁻¹ K⁻¹
T= 0°C or 273 K
Putting all the values in the equation will give:
[tex]1\times V=0.98\times 0.0821\times 273[\tex]
V = 22 L
So the answer is 22 L.
