Question

The volume of $0.5$ mole of gas at $1$ atm pressure and ${273}^{o}C$ temperature is :

• A. $22.4$
• B. $11.2$
• C. $44.8$
• D. $5.6$

Answer 1

The correct option is A $22.4$

$Volume=V=?$

$Pressure=P=1atm.$

$Temperature=t={273}^{o}C$

$\Rightarrow T=546K$

where R is universal gas constant with a value of 0.0821 lit-atm/mol/kelvin.

$\Rightarrow V=\frac{nRT}{P}.....\left(1\right)$

Substituting the value from the data in equation (1), we get

$V=\frac{0.5\times 0.0821\times 546}{1}=22.4litres$
