What is the boiling point (in °c) of a solution of 7.94 g of i2 in 69.2 g of toluene, assuming the i2 is nonvolatile? (for toluene, tb = 110.63°c and kb = 3.40°c·kg/mol.)

The boiling point of  solution is

Explanation:

Elevation in boiling point:

where,

= boiling point of solution = ?

= boiling point of toluene =

= boiling point constant of toluene =

m = molality

i = Van't Hoff factor = 1 (for non-electrolyte)

= mass of solute = 7.94 g

= mass of solvent (toluene) = 69.2 g

= molar mass of solute = 254g/mol

Now put all the given values in the above formula, we get:

Therefore, the boiling point (in °C) of a solution is 112.16

it would be c. predictability
