16 g of O2 was filled in a container of capacity 8.21 litres at 300 K. Calculate Pressure exerted by O2 in atm.( Write your answer after multiplying 10 .

The number of moles of oxygen are n=16g32g/mol=0.5molThe pressure exerted by oxygen gas is P=nRTV=0.5×0.0821×3008.21=1.5atm.

16 $g$ of $O_{2}$ was filled in a container of capacity 8.21 litres at 300 $K$ . Calculate Pressure exerted by $O_{2}$ in $a t m$ .( Write your answer after multiplying 10 .

The number of moles of oxygen are $n = \frac{16 g}{32 g / m o l} = 0.5 m o l$
The pressure exerted by oxygen gas is $P = \frac{n R T}{V} = \frac{0.5 \times 0.0821 \times 300}{8.21} = 1.5 a t m$ .
