The balanced chemical equation can be written as:- C2H4N2 + 3O2 ? 2CO2 + 2H2O + N2 (9-v) v 4 6 2 (i) The GAY LUSSAC'S LAW ,according to which the reactants are in whole number ratio which is equal to the mole ratio. (9-v)/v=1/3 27-3v=v 27=4v v=6.75mL (ii) The molecular mass of compound A i.e. C2H4N2=(2×12)+(4×1)(2×14)=56g/mol.
