Chapter 17, Problem 118AE

Interpretation Introduction

Interpretation:

The mass of a nonelectrolyte solute dissolved in 150 ml of a solvent needs to be deduced under the given conditions.

Concept Introduction:

The elevation in boiling point ( ${\text{ΔT}}_{\text{b}}$ ) of a solution in the presence of a solute of molality ( m ) is given as:

  $\begin{array}{l}{\text{ΔT}}_{\text{b}}{\text{ = T}}_{\text{b}}-{\text{T}}_{\text{b}}^{\text{0}}\\ {\text{ΔT}}_{\text{b}}{\text{=i(K}}_{\text{b}}\text{×m) ----(1)}\end{array}$

Here,

  ${\text{ΔT}}_{\text{b}}$ andT_b are the boiling points of the pure solvent and solution respectively.

K_b denotes the boiling point elevation constant.
