Calculate the activity co-efficient?
The solubility of gaseous O2 at a partial pressure of 1.01 bar and a temperature of 310.2K, ex- pressed as a concentration, is 1.07 *10-3 mol dm-3 in pure water and 4.68*10-4 mol dm-3 in a 3.0 M aqueous solution of KCl.17 This solubility decrease is the salting-out effect. Calculate the activity co-efficient γc,B of O2 in the KCl solution.
