Chapter 5, Problem 85E

Interpretation Introduction

Interpretation: The density of uranium hexafluoride is to be calculated at ${60}^{\circ }C$ and 745 torr. (The boiling point of ${\text{UF}}_{\text{6}}$ is ${56}^{\circ }C$)

Concept introduction:

Boiling point is the temperature at which the liquid compound will boil and transform to gaseous state.

Molecular mass of compound is sum of atomic mass of each atoms constituted in the compound.

Equation for density is,

       $\text{Density}\text{=}\frac{\text{Mass}}{\text{Volume}}$

According to ideal gas equation,

$\text{Pressure}\text{×}\text{Volume}\text{=}\frac{\text{Mass}\text{×}\text{R}\text{×}\text{Temperature}}{\text{Molecular}\text{mass}}$

Ideal gas equation in terms of Density,

                 $\text{Density}\text{=}\frac{\text{Pressure}\text{×}\text{Molecular mass}}{\text{R}\text{×}\text{Temperature}}$
