BALGANESH

total no of moles = 8

40% = 3.2 moles of the mixture

now this 3.2 moles of mixture contain 0.8 mole of N2 rest H

N2 + 3H2 = 2NH3

now 1 mole ofN2 reacts with 3 mole of H2 therefore 0.8 mole of N2 will react with 2.4 mole of H2 which is present

therefore from the reaction 1mole N2 = 2 mole of NH3

0.8 mole of N2 = 1.6 mole of NH3
