35.8 L
According to the combined gas law: pV=nRT
p=pressure
V=volume
T=temperature in Kelvin
R=the universal gas constant
n=number of moles of the gas
Rearranging the equation: n= pV/RT
n=(153.3kPa)(25.5L)/R(298K)= 13.1/R
At STP (standard temperature and pressure) p=100kPa and T=273.15K.
Rearranging the equation again: V=nRT/p V=[(13.1/R)(R)(273.15K)]/100kPa = 35.8L
