Homework Help: Chemistry, Need to know

  1. Jan 12, 2010 #1
    The Question is
    Ammonia is formed by the reaction of nitrogen and
    N2(g) + 3H2(g) → 2NH3(g)
    Calculate the maximum mass of ammonia that
    could be produced when 6.00 L of nitrogen gas at
    SLC reacts with excess hydrogen gas.

    The Answer is
    n(N2) = = mol
    n(NH3) = 2 × n(N2)
    m(NH3) = n × M = = 8.33 g

    i don't know why the 2 in the step 2 of the answer is there. I really need to know as i don't understand why it is there, and i cannot ask my teacher as i am on holidays.
