Chapter 14.4, Problem 53SSC

Interpretation Introduction

Interpretation:

The solution molality has to be calculated by using the given data of boiling point elevation.

Concept introduction:

Boiling point elevation is calculated as follows:

$\Delta {\mathrm{T}}_b=K_b\times m$

Here,

$\Delta T_b=T_{b}ofthesolution-T_{b}ofthesolvent(Water)$

Answer to Problem 53SSC

The solution molality found to be 2.19m for the non-volatile

Boiling point elevation $\Delta T_b=K_b\times m$

Data given:

K_b of water = 0.512 $°C/m$

Δ T_b=1.12 °C

Boiling point elevation $\Delta T_b=K_b\times m$

$1.12=0.512\times m$

m=2.19m

The solution molality found to be 2.19m for the non-volatile.

Explanation of Solution

Boiling point elevation $\Delta T_b=K_b\times m$

Data given:

K_b of water = 0.512 $°C/m$

Δ T_b=1.12 °C

Boiling point elevation $\Delta T_b=K_b\times m$

$1.12=0.512\times m$

m=2.19m

The solution molality found to be 2.19m for the non-volatile.
