Chapter 7, Problem 7.8E

Interpretation Introduction

Interpretation:

The minimum amount of ${\text{H}}_{\text{2}}\text{O}$ needed to ensure that there is a liquid phase in equilibrium with a vapor phase and the minimum amount of ${\text{CH}}_{\text{3}}\text{OH}$ needed to ensure a liquid phase and vapor phase under the same conditions is to be stated.

Concept introduction:

The ideal gas law defines the ideal behavior of gases or vapors of the system. This law is stated by the formula given below.

$PV=n\text{R}T$

In the above equation, $P$ is the pressure of gas or vapors, $V$ is volume of the gas or vapors, R is the gas constant, $T$ is the temperature and $n$ is the number of moles of the gas or vapors.
