The equation that can be used to calculate the volume is the ideal gas equation. This is only valid for use for gases. It is expressed as:
PV = nRT
where P is the pressure, V is the volume, n is the amount in moles of the gas, R is the universal gas constant and T is the temperature.
At constant pressure, the calculations are as follows:
T1 / V1 = T2 / V2
V2 = T2 x V1 / T1
V2 =373.15 x 5.0 / 323.15
V2 = 5.77 L
