1.	A vessel contains double thenumber of moles ofhydrogen than oxygen. Due to a hole in thevessel, one-fouth of the gaseous mixture is effused out. What is the ratio of the number of moles of hydrogen and oxygen remaining in thevessel ?
Answer» SOLUTION :(i) relation between number of moles of gases (ii) relation between number of moles of gases effused and molecular WEIGHT (iii) comparison of number OFMOLES of `H_(2) and O_(2)` effused (IV) calculation of number of moles of `H_(2) and O_(2)` left over (v) ` 28 : 17`
