Chapter 5.1, Problem 5.5PP

(a)

Interpretation Introduction

Interpretation:

Moles of hydrogen that is required to fill a $\text{100}\text{.0}\text{L}$ container has to be calculated.

Concept Introduction:

At constant temperature and pressure, the volume of gas and the number of moles of gas is related using the Avogadro’s law.  Same number of moles is present in ideal gas with equal volume if the measurement is done at same temperature and pressure.  This can be expressed in the equation form as,

    $\frac{V}{n}=K_a$

Where,

    $n$ is the number of moles of gas.

    $V$ is volume of gas.

    $K_a$ is a constant.

Initial and final conditions can be related using the Avogadro’s law as shown below,

    $\frac{V_i}{n_i}=\frac{V_f}{n_f}$

(b)

Interpretation Introduction

Interpretation:

Moles of hydrogen that is required to triple the volume that is occupied by $\text{0}\text{.25}\text{mol}$ of hydrogen has to be calculated.
