Chemistry question please?Urgent :/

  1. Dec 11, 2012 #1
    In a dish with the volume 1 litre we have 0.3 moles of nitrogen, 0.4 moles of hydrogen and 0.1 moles of amoniac. How many moles of hydrogen should we add to the dish so we can double the concentration of the balance for amoniac,if the temperature does not change?
    So I find the concentrations by the formula C=n/V and they are respectively 0.3 0.4 0.1..now I dont know how to put the equation in the state of change...
