Chapter 10, Problem 24PS

Interpretation Introduction

Interpretation:

The density of diethyl ether in a flask at $\text{25°C}\text{and}\text{a}\text{pressure}\text{of}\text{233}\text{mm}\text{Hg}$ has to be given.

Concept Introduction:

Density of a gas can be find out with the help of ideal gas equation which is

  $\text{PV}\text{=}\text{nRT}$

n in the given equation can be written as $\frac{\text{m}}{\text{M}}$ Since amount of any substance is given by dividing mass with molar mass.

  $\begin{array}{l}\text{PV}\text{=}\frac{\text{m}}{\text{M}}\text{RT}\\ \frac{\text{m}}{\text{V}}\text{=}\frac{\text{PM}}{\text{RT}}\\ \text{density}\text{=}\frac{\text{PM}}{\text{RT}}\end{array}$
