A 4: 1 molar mixture of He and CH4 is contained in a vessel at 20 bar pressure. Due to a hole in the vessel, the gas mixture leaks out. What is the composition of the mixture effusing out initially?

A 4 : 1 molar mixture of He and CH_(4) is contained in a vessel at 20 bar pressure. Due to a hole in the vessel, the gas mixture leaks out. What is the composition of the mixture effusing out initially?

A 4 : 1 mixture of helium and methane contained in a vessel at 10 bar pressure. During a hole in the vessel, the gas mixture leaks out. The composition of the mixture effusing out initially is

A 3:2 molar mixture of N_(2) and CO is present in a vessel at 500 "bar" pressure. Due to hole in the vessel, the gas mixture leaks out. The composition of mixture effusing out initially is

O_(2) and He are taken in equal weights in a vessel. The pressure exerted by Helium in the mixture is

The total pressure of a mixture of oxygen and hydrogen is 1.0 atm. The mixture is ignited and the water is removed. The remaining gas is pure hydrogen and exerts a pressure of 0.40 atm when measured at the same values of T and V as the original mixture. What was the composition of the original mixture in mole fraction ?

A gaseous mixture (He and CH_(4)) which has density (64)/(246.3) gm/litre at 1 atm & 300 K is kept in a container. Now a pinhole is made on the wall of the container through which He(g) and CH_(4) effuses. What will be the composition of the gas mixture [n_(He) : n_(CH_(4))] effusing out initially?

A mixture of 50mL of H_(2) and 50mL of O_(2) is allowed to effuse through an effusiometer till the residual gas occupies 90 mL . What is the composition of ( a ) effused gas, ( b ) the residual gas?

Ten millilitre of a mixture of CO,CH_4 , and N_2 exploded with an excess of O_2 and gave a contaction of 6.5ml . When the residual gas was treated with NaOH , there was further contraction of 7 ml. What is the composition of the original mixture?

A mixture of two gases A and B in the mole ratio 2:3 is kept in a 2 litre vessel. A second 3 litre vessel has the same two gases in the mole ratio 3:5 . Both gas mixtures have the same temperature and same pressure. They are allowed to intermix and the final temperature and pressure are the same as the initial values, the final volume beingh 5 litres. Given theat the molar masses are M_(A) and M_(B) . what is the mean molar mass of the final mixture :

A gas is enclosed in a vessel at a constant temperature and at a pressure of 2 atm and volume 4 liters. Due to a leak in the vessel after some time the pressure is reduced to 1.5 atm as a result if 5P% of the gas escaped out then find the value of P.
