Chlorine is produced from sodium chloride by the electrochemical chlor-alkali process. During the process, the chlorine is collected in a container that is isolated from the other products to prevent unwanted (and explosive) reactions. If a 15.50-L container holds 0.5950 kg of Cl₂ gas at 225°C, calculate:
(b) Pvdw (Use R = 0.8206(atm.L/mol.K) )
