    Calculate the partial pressure of all gases after the reaction?
    Consider the following reaction:

    4NH3 + 5 O2--> 4NO + 6H20

    Suppose that 1.00x 10^-2 mol of NH3 and 2.00x 10^-2 mol of O2 are pumped into a 3.00L tank at STP.

    a) Calculate the mole fraction of NH3 and O2 before the reaction occurs.

    b) Calculate the partial pressure of all gases after the reaction is complete (assume that the temperature and the volume remain constant)

    1) Mole Fraction of NH3 = number of moles of NH3 x 100 / Total number of moles
    Total number of moles = no. of moles of NH3 + no. of moles of O2

    Do it similarly for O2.
