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.
