Question

A closed vessel of capacity 1m³ contains 0.9 kg of water and 1.6 kg of oxygen. The pressure in the vessel at a temperature of 500 K is (R = 8 J mol^-1k^-1)

Moderate

A

400 Kpa
B

160 Kpa
C

300 Kpa
D

200 Kpa

Solution

no. of moles of water $= \frac{900}{18} = 50$
no. of moles of $O_{2} = \frac{1600}{32} = 50$
$P = \frac{nRT}{V} = \frac{100 \times 8 \times 500}{1} = 40 \times 10^{4} Pa = 400 KPa$
