Chapter 14, Problem 4PE

Interpretation Introduction

Interpretation:

The effective molar mass of air-the mass per mole of mixed molecules which is found to have a mass of $\text{0}\text{.59 g}$ in a $\text{0}\text{.50-}$ liter container at the temperature of $\text{22}°\text{C}$ and the pressure of $\text{0}\text{.988 atm}$ is to be determined.

Concept Introduction:

The ideal gas law is the compilation of Charles’s Law $\left(\text{V}\propto \text{T}\right)$, Boyle’s Law $\left(\text{V}\propto \frac{\text{1}}{\text{P}}\right)$ and Avogadro’s Law $\left(\text{V}\propto \text{n}\right)$.

The ideal gas equation resultant of all the ideal gas law’s is shown below.

$\text{PV}=\text{nRT}$

Effective molar mass is the average of molar mass of mixture of gases.
