A mixture of NH_(3(g)) and N_(2)H_(4_((g))) is placed in a sealed container at 300 K . The total pressure is 0.5 atm . The container is heated to 1200 K , at which time both substances decompose completely according to the equations: 2NH_(3(g))rarrN_(2(g))+3H_(2(g)) N_(2)H_(4_((g)))rarrN_(2(g))+2H_(2(g)) After decomposition is complete, the total pressure at 1200 K is found to be 4.5 atm . Find the amount (mole) per cent of N_(2)H_(4(g)) in the original mixture.
