Chapter 17, Problem 79E

Interpretation Introduction

Interpretation : The mole fraction of NaCl in the solution should be calculated. The vapor pressure of the solution at 45 ⁰C should be calculated.

Concept Introduction :

Raoult’s law;

  $P_{so\ln }=X_{solvent}{P}^0{}_{solvent}$

  $\begin{array}{l}{P}_{so\ln }\text{ - observed vapor pressure of the solution}\\ X_{solvent}\text{ - mole fraction of the solvent}\\ P^0{}_{solvent}\text{ - vapor pressure of the pure solvent}\end{array}$
