Question

Helium gas was allowed to enter through a pinhole into a vessel of 112 litres at 0°C till the pressure reads 2 atm. Then methane and SO2 gases are introduced into the same hole under similar conditions till pressure increases to 5 atm. The mole fraction of methane in the total mixture was found to be 0.4.

1)Partial pressure of SO2 in the mixture is?

2)Amount of CH4 in the mixture is?
