1.22 g of a monobasic acid is dissolved in 100 g of benzene. Boiling point of solution increases by 0.13ºC with respect to pure benzene. Find the molecular mass of acid in benzene solvent (in u). Report your answer after dividing it by 100 and Round it off to nearest integer.(K b of benzene = 2.6 K kg mol –1 ).
Text Solution
Verified by ExpertsThe correct answer is:
2
(2)
Δ T b = K b × m
0.13 = 2.6 × 
∴ M = 244 u
∴ Reported answer = 2
