Chapter 1, Problem 1.8P

(a)

Interpretation Introduction

Interpretation:

The partial pressure of given gases sample has to be calculated.

Concept Introduction:

Ideal gas law:

The relationship between pressure, temperature and volume of a gas given by ideal gas law,

  $\begin{array}{l}\text{PV}\text{=}\text{nRT}\\ \text{Where,}\\ P\text{-}p\text{ressure}\\ {\text{T}}_{}\text{-temperature}\\ {\text{V}}_{}\text{-volume}\\ \text{n-number of mole}\end{array}$

Mole fraction:

Mole fraction is given by mole of sample divide by total mole of the mixture.

    $X_{sample}=\frac{Molesample}{Totalmolemixture}$

Partial pressure:

The pressure extracted by an individual gas in a mixture is known as partial pressure, the sum of partial pressures of individual gasses in a mixture gives the total pressure of a mixture.

The partial pressure of any gas is defined as,

  $\begin{array}{l}{p}_{sample}\text{=}{\text{x}}_{sample}{\text{P}}_{\text{total}}\\ \text{Where,}\text{x-}\text{mole}\text{fraction}\text{in}\text{a}\text{mixture,}\text{P-}\text{total}\text{pressure}\end{array}$
