Q. A $10.0 L$ flask contains $64 g$ of oxygen at $2 7^{\circ} C$ . (Assume $O_{2}$ gas is behaving ideally). The pressure inside the flask in bar is (Given $R = 0.0831 L ba r K^{- 1} m o l^{- 1}$ )

$4.9$

$2.5$

$498.6$

$49.8$

$V = 10 L$
$W_{O_{2}} = 64 g$
$T = 2^{\circ} C$
$n_{O_{2}} = 2$
$R = 0.083. L$ bar $K^{- 1} m o l^{- 1}$
Ideal gas equation $P V = n RT$
$P = \frac{2 \times 0.0831 \times 300}{10}$
$P = 4.9$ bar
