The correct option for the total pressure (in atm) in a mixture of 4 g O2 and 2 g H2 confined in a total volume of one liter at 0C is :
[Given R=0.082 L atm mol-1 K-1, T=273 K]
1. 25.18
2. 26.02
3. 2.518
3. 2.602
The volume occupied by 1.8 g of water vapour at 374 and 1 bar pressure will be -
[Use R=0.083 bar ]
1. 96.66 L
2. 55.87 L
3. 3.10 L
4. 5.31 L
The pressure exerted by 6.0 g of methane gas in a 0.03 m3 vessel at 129 ºC is:
(Atomic masses : C = 12.01, H = 1.01 and R = 8.314 JK–1mol–1)
1. 13409 Pa
2. 41648 Pa
3. 31684 Pa
4. 215216 Pa
