4NH3+5O2->4NO+6H2O

    Lets check to see if there is a limiting reageant.

    Four volumes of ammonia, five volumes of O2
    5/4 *34.5=43 L O2, so there is not enough oxygen.
    4/5*39.5=31.6 L of ammonia are reacted.
    Liters of NO produced: 31.6L NO
    moles: 31.6/22.4
    You figure the grams.
