Expert Answer
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
Calculating molality of the solution:
Molar mass of acetic acid = 60 g/mol
Thus,
Substituing the values in the expressi...
