n = n O 2+ n H 2 n =(4/32)+(2/2) n =(9/8) P =( nRT / V ) P =(9/8) × (0.0821 × 273/1) =25.18 atm

Q. Choose the correct option for the total pressure (in atm.) in a mixture of $4 g O_{2}$ and $2 g H_{2}$ confined in a total volume of one litre at $0^{\circ} C$ is : $[$ Given $R = 0.082 L a t m m o l^{- 1} K^{- 1}, T = 273 K]$

$2.518$

$2.602$

$25.18$

$26.02$

$n = n_{O_{2}} + n_{H_{2}}$
$n = \frac{4}{32} + \frac{2}{2}$
$n = \frac{9}{8}$
$P = \frac{n RT}{V}$
$P = \frac{9}{8} \times \frac{0.0821 \times 273}{1}$
$= 25.18 a t m$
