# 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?

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: $\Delta {T}_{b}$

$\Delta {T}_{b} = i {K}_{b} m$

$i \left[C a {\left(N {O}_{3}\right)}_{2}\right] \approx 3$

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.
