Chapter 13, Problem 13.61QP

Interpretation Introduction

Interpretation: Amount of Urea added to $\text{658g}$ of water to make a solution with vapor pressure of $\text{2}\text{.50mmHg}$ to be calculated.

Concept introduction

Raoult’s law states that in an ideal mixture of liquid solution, partial pressure of every component is equal to its mole fraction multiplied into vapor pressure of its pure components.

${\text{P}}_{}{\text{= χ}}_{}{\text{P}}^{\text{°}}$

Where,

P- Partial pressure of each component

$\text{P°-}$ Partial pressure of its pure components

${\text{χ}}_{\text{1}}$- Mole fraction of the components
