    You get 1/3 moles of NO for each mole of NO2.

    Therefore, you get 1/3x8.44= 2.81 moles of NO

    First we know we have 8.44moles of NO2 and there is a 1 to 3 mole ratio of NO to NO2 so to calculate the moles NO we just set up the following equation:

    moles NO =moles NO2 x 1 mole of NO/3 Moles NO2
