Acetic acid has a boiling point of 118.5 deg C and a #K_b# of 3.08 C/m. What is the boiling point of a 3.20 m solution of #Ca(NO_3)_2# in acetic acid?

Answer:

The solution's boiling point is approximately #148.1°C#.

Explanation:

#T_b[HC_2H_3O_2] = 118.5°C#

We want to find the boiling point elevation: #DeltaT_b#

#DeltaT_b = iK_bm#

#i[Ca(NO_3)_2] approx 3#

#DeltaT_b = 3*3.20m*(3.08°C)/m approx 29.6°C#

Add this to the pure solvent's boiling point, and that's your answer.
