Determine the boiling point of a 3.70 m solution of phenol in benzene. Benzene has a boiling point of 80.1°C and a boiling point elevation constant of 2.53°C•kg/mol.

The boiling point of a 3.70 m solution of phenol in benzene is

Explanation:

Elevation in boiling point:

where,

= change in boiling point

i= vant hoff factor = 1 (for benzene which is a non electrolyte )

= boiling point constant =

m = molality = 3.70

Thus  the boiling point of a 3.70 m solution of phenol in benzene is

they are all solids.
