A 4:1 mixture of helium and methane is contained in a vessel at 10 bar

1.	A 4:1 mixture of helium and methane is contained in a vessel at 10 bar pressure. Due to a hole in the vessel, the gas mixture leaks out. The composition of the mixture effusing out initially is
Answer» `8:1` `8:3` `4:1` `1:1` Solution :Pressure of helium=8 BAR Pressure of `CH_(4)=2` bar `(r_(He))/(r_(CH_(4)))=(P_(1))/(P_(2))sqrt((M_(CH_(4)))/(M_(He)))=(8)/(2)sqrt((16)/(2))=(8)/(1)=8:1`
