Chapter 16, Problem 124E

Interpretation Introduction

Interpretation:

The molality of the solution and the value of ${\text{K}}_{\text{b}}$ for the solvent when $\text{14}\text{.56}\text{g}$ of TNT, ${\text{C}}_{\text{7}}{\text{H}}_{\text{5}}{\text{N}}_{\text{3}}{\text{O}}_{\text{6}}\left(227.1\text{g/mol}\right)$, is dissolved in $\text{264}\text{.3}\text{g}$ of an organic solvent are to be calculated.

Concept introduction:

Molality is defined as the measure of concentration of moles of solute in a solution. It is calculated by dividing the number of moles of solute by the weight of solvent in $\text{Kg}$.

Colligative properties are defined as the physical properties of some dilute solutions which depend on the molal concentration of the solutes.
