2.41 Determine the osmotic pressure of a solution prepared by dissolving of in of water at assuming that it is completely dissociated.
Dissociation of K2SO4 is as follows :-
It is clear that 3 ions are produced, so the value of i will be 3.
Molecular weight of K2SO4 = 2(39) + 1(32) + 4(16) = 174u.
Putting all the values :-
