36% of a solute is trimerised in a solution. Van't Hoff factor of the solute in the solution is

Due to association, number of particles decreases…. i < 1….always ; Van't Hoff factor,  i=1-α+αn ; n=2…..dimerisation….i=1-α2; n=3…..trimerisation….i=1-2α3; n=4…..tetramerisation….i=1-3α4;α= Degree of association ;α for x% associated solute = x100;  n=3…..trimerisation….i=1-2(0.36)3; i=0.76 ;
