1.according to the ideal gas law, a 1.052 mol sample of methane gas in a 1.031 l container at 271.3 k should exert a pressure of 22.72 atm. by what percent does the pressure calculated using the van der waals' equation differ from the ideal pressure? for ch4 gas,
a = 2.253 l2atm/mol2 and
b = 4.278×10-2 l/mol.
