Question

Assuming ideal solution behavior, what is the boiling point of a 033m solution of a nonvolatile solute in benzene?

Answer 1

$\Delta T_b=k_b.M$

$k_b=2.53°cM^{-1}$

Boiling point of Benzene$=80.1°c$

Concentration $=0.33M$

$\Delta T_b=2.53×0.33=0.8349°c$

Boiling point$=80.1+0.8349=80.9349°c$
