Question

When $28g$ of nitrogen gas occupying a volume of $22.4L$ at $0^{o}C$ and $1atm$. pressure was heated to ${273}^{o}C$ the pressure became $2atm$. The new volume of the gas in litres is :

• A. $44.8$
• B. $11.2$
• C. $22.4$
• D. $89.6$

Answer 1

The correct option is C $22.4$

$\frac{P_1{V}_1}{T_1}=\frac{P_2{V}_2}{T_2}$

$\frac{1\left(22.4\right)}{273}=\frac{2\left(V_2\right)}{546}$

$V_2=22.4L$

The new volume of the gas is 22.4 litres.

So answer is C.
