Interpretation Introduction

Interpretation:

The number of green spheres is to be determined and the mole fraction of green and yellow spheres is to be calculated.

Concept introduction:

The mole fraction of an individual gas in a combination of gases is the ratio of moles of the individual gas with the aggregate moles of the combination. This can be shown by:

${\chi }_i=\frac{n_i}{n_{\text{total}}}$

Here, ${\chi }_i$ is the mole fraction of individual gas $i$, $n_i$ is the number of moles of $i$, and $n_{\text{total}}$ is the total number of moles.

Number of moles is defined as the ratio of mass to the molar mass.
