Chapter 8.6, Problem 8.13E

Interpretation Introduction

Interpretation:

Amount of $Ar$ present in the gas sample has to be determined using the given data.

Concept Introduction:

Molar mass can be determined using the given equation,

  $\text{n}\text{= }\frac{\text{m}}{\text{M}}$

Here, n is the number. of moles

  M is the Molar mass

    m is the Mass

Ideal gas Equation:

Any gas is described by using four terms namely pressure, volume, temperature and the amount of gas. Thus combining three laws namely Boyle’s, Charles’s Law and Avogadro’s Hypothesis the following equation could be obtained. It is referred as ideal gas equation.

  $\begin{array}{l}\text{V }\propto \frac{\text{nT}}{\text{P}}\\ \\ \text{V = R}\frac{\text{nT}}{\text{P}}\\ \\ \text{PV = nRT}\end{array}$

Here,

  n is the moles of gas

    P is the Pressure

  V is the Volume

    T is the Temperature

    R is the gas constant

Total pressure of a flask containing mixture of gases is the sum of individual partial pressures of constituted gases.
