Question

For different ideal gases $\left(d/P\right)$ versus $P$ variations at definite temperature is:

• A.
• B.
• C.
  
• D.

Answer 1

The correct option is C


$\left(\frac{d}{P}\right)=\frac{M}{RT}=\text{constant}$

So, $\frac{d}{P}$ values remain constant with regular increase in $P$. The higher curve corresponds to higher molar mass.
