Question

on dissolving
2.34g of a non-volatile solute in
40g of
benzene, the boiling point of
Solution was
higher than
that of benzene
by 0.81k. Kb for
benzene is 2.53k Kkg/mol.
Calculate the molar mass of non - Volatile
Solute​

Answer 1

Answer:

182.77

Explanation:

The relation for elevation in B.P is ΔTb=Kb.m (m is molality)

⇒0.81=2.53 × (2.34/x) × (1000/40) (x is molar mass of solute)

m=182.77
