Chapter 11, Problem 105AE

Interpretation Introduction

Interpretation: The mass percentage of the solution has to be calculated.

Concept Introduction:

The changes in boiling and freezing point are by given by the modified equation that is used to determine the colligative properties of strong electrolytes. The van’t Hoff factor in the equation is given by,

$\text{ΔT=imK}$

Where, K= change in boiling/freezing point

                      i=Van’t Hoff factor that takes the equation,

$\text{i=}\frac{\text{moles}\text{of}\text{particles}\text{in}\text{solution}}{\text{moles}\text{of}\text{solute}\text{dissolved}}$

Mass percent of compound can be given by calculated mass of the compound to the total mass whole multiplied by $\text{100}$.

$\text{Mass}\text{percent(\%)=}\frac{\text{Calculated}\text{mass(g)}}{\text{Total}\text{mass(g)}}\text{×100}$
