A vessel of volume 20L contains a mixture of hydrogen and helium at temperature 27^∘C and pressure 2atm. The total mass of the mixture is 5g. Assuming ideal gases, the ratio of mass of hydrogen to that of helium is
A vessel of volume 20L contains a mixture of hydrogen and helium at temperature 27^∘C and pressure 2atm. The total mass of the mixture is 5g. Assuming ideal gases, the ratio of mass of hydrogen to that of helium is
Show Hint
For gas mixtures:
• Use molar mass carefully.
• Partial moles determine mass ratios.
- \(1:2\)
- \(2:3\)
- \(2:1\)
- 2:5
The Correct Option is B
