21i for acetone = 1;
MW = 122g/mol
i for benzene = 0.5
MW = 244g/mol
1.22g of benzoic acid is dissolved in 100 g of acetone and 100g of benzene seperately. Boliing point of the solution in acetone increases by 0.17 degree C, while that inthe benzene increases by 0.13 degree C;
Kb for acetone and benzene is 1.7 K kg / mol and 2.6 K Kg / mol
Find the molecular weight of benzoic acid in two cases and justify your answer...
