Mole concept....Simple prob..
None

60 ml of a mix of NO and N2O was exploded with excess of H2 If 38ml of N2  was forme cal, the vol of each gas in the mix....plz solve and post the soln to get rated,,,,

The reaction is NO + N2O + H2 = N2 + H2O
Apply POAC for N. let x be the vol of NO in the mix. then N2O= 60-x
x+ 2(60-x) = 2x38
solving for x, we get x= 44
so, NO= 44ml & N2O= 16ml

POAC is Principle of Atom Conservation. Its a really useful method to solve mole concept problems. no need to balance & all just requires simple equations for calculations. Read R C Mukherjee.
