Question

The equation of state corresponding to 8g of $O_{2}$ is

• A. $PV = 8RT$
• B. $PV = RT/4$
• C. $PV = RT$
• D. $PV = RT/2$

Answer 1

Answer: (B)

$PV = RT/4$

Answer 2

As 32 gm $O_{2}$ means 1 mole therefore 8 gm $O_{2}$ means 1 / 4mole i.e. $\mu = \frac{1}{4}$

So from $PV = \mu RT$ we get $PV = \frac{1}{4}RT$ or $PV = \frac{RT}{4}$
