we can use the ideal gas law equation to find the volume occupied by the gas
PV = nRT
where
P - standard pressure - 101 325 Pa
V - volume
n - number of moles - 0.881 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - standard temperature - 273 K
substituting the values in the equation
101 325 Pa x V = 0.881 mol x 8.314 Jmol⁻¹K⁻¹ x 273 K
V = 19.7 L
volume of the gas is 19.7 L
