we can use the ideal gas law equation to find the volume occupied by CO₂
PV = nRTwhere P - pressure - standard pressure is 101 325 Pa
V - volume
n - number of moles - 25.0 g / 44 g/mol = 0.568 mol
R - universal gas constant - 8.314 Jmol⁻¹K⁻¹
T - temperature - standard temperature is 273 K
substituting the values in the equation
101 325 Pa x V = 0.568 mol x 8.314 Jmol⁻¹K⁻¹ x 273 K
V = 12.7 L
volume of the container is 12.7 L
