(a)

Interpretation Introduction

Interpretation:

The $\%\left(\frac{m}{m}\right)$ of oxygen gas in a mixture containing $20g$ of oxygen gas and $80g$ of nitrogen gas has to be calculated.

Concept Introduction:

The mass $/$ mass percent composition or $\%\left(\frac{m}{m}\right)$ can be calculated using the following formula.

    $\%\left(\frac{m}{m}\right)=\frac{gofsolute}{gofsolution}\times 100\%$

(b)

Interpretation Introduction

Interpretation:

The $\%\left(\frac{m}{m}\right)$ of argon gas in a mixture containing $50g$ of argon gas and $80g$ of helium gas has to be calculated.
