Expert Answer

Step 1

When a solute is added to a solvent, elevation in boiling point occurs.The expression relating the change in temperature with molality (m) of solute is given below.

Where, 

T= Boiling point of the solution formed

T0= Boiling point of the solvent

kb = molal boiling point elevation constant

m= molality of the solution

Step 2

Calculating molality of the solution:

Molar mass of acetic acid = 60 g/mol

Thus,
