Chapter 5, Problem 5.64QP

Interpretation Introduction

Interpretation:

Mass of helium in grams that has to be added to balloon in order to double its volume that contains $\text{8}\text{.00}\text{g}$ has to be calculated.

Concept Introduction:

Avogadro’s law states that under the same condition of pressure and temperature for any ideal gas of equal volume, it contains the same number of moles in it.  In the form of equation this can be expressed as,

    $\frac{V}{n}=k_a$

Where,

    $V$ is the volume.

    $n$ is the number of mol.

    $k_a$ is Constant.

The initial condition and final condition can be related in Avogadro’s law by the equation given below,

    $\frac{V_i}{n_i}=\frac{V_f}{n_f}$
