Chapter 13, Problem 13.20P

Interpretation Introduction

Interpretation:

Mass of radon in $\text{7}\text{.12 μL}$ container at a pressure of $8.72\times {10}^4\text{ Pa}$ and $\text{22 }°\text{C}$ has to be calculated.

Concept Introduction:

The combination of all the gas laws namely Boyle’s law, Charles law and Avogadro’s leads to the ideal gas equation that can be used to relate all the four properties such as given below:

  $PV=nRT$        (1)

Here,

$\text{R}$ denotes gas constant.

$V$ denotes the volume.

$n$ denotes the temperature.

$P$ denotes the pressure

The formula to convert moles to mass in grams is as follows:

  $\text{Mass}=\left(\text{Number of moles}\right)\left(\text{molar mass}\right)$
