Chemistry

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)â†’N2(g)+3H2(g)Â Â ;N2H4(g)â†’N2(g)+2H2(g) . Afterdecomposition is complete the total pressure at 1200KÂ Â 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.
