A mixture of NH3(g) and N2H4(g) is placed in asealed container at 310 K . The total pressure is 0.48 atm . Thecontainer is heated to 1200 K at which time both substancesdecompose completely according to the equations2NH3(g)→N2(g)+3H2(g)  ;N2H4(g)→N2(g)+2H2(g) . Afterdecomposition is complete the total pressure at 1200K  is found to be 4.5 atm.
Find the percent amount (moles) of N2H4(g) in theoriginal mixture. (Assume two significant figures for thetemperature.)
Express your answer using two significant figures.
