# Problem: A 2.4 m aqueous solution of an ionic compound with the formula MX2 has a boiling point of 103.4 oC. Calculate the van't Hoff factor (i) for MX2 at this concentration.

###### FREE Expert Solution

The change in boiling point is also related to the molality of the solution:

$\overline{){\mathbf{∆}}{{\mathbf{T}}}_{{\mathbf{b}}}{\mathbf{=}}{{\mathbf{iK}}}_{{\mathbf{b}}}{\mathbf{m}}}$

where:

i = van’t Hoff factor

m = molality of the solution (in m or mol/kg)

Kb = boiling point elevation constant (in ˚C/m)
