The ideal gas law provides one way to estimate the pressure exerted by a gas in a container. The law is

More accurate estimates can be made with the van der Waals equation

For chlorine ( Cl ), = 0.6343 [ Pa⋅m ] and = 5.62 × 10 −5  [ m ] (Reid et al, 1987). Compare the

pressure estimates given by the ideal gas law and the van der Waals equation for 1 mol of Cl 2   in 22.41
