In the reaction N2 + 3H2 -> 2NH3, how many grams of NH3 gas would be formed when H2 gas, having a volume of 11.2 liters at STP, reacts with excess N2 gas?

Completly confused, thank you very much for your help :)

  1. Here is a link that will show you how to work stoichiometry problems.

    There is a shortcut that can be used when all of the reactants and products are gases. You may consider volumes as moles. That way it looks like this.
    11.2 L H2 x (2 moles NH3/3 mole H2) = 11.2 x (2/3) = xx L NH3.
    Then convert xx L NH3 to grams remembering that 22.4 L NH3 has a mass of 17 grams (1 mole).

  2. Given the following chemical reaction:

    N2 + 3H2 → 2NH3

    How many grams of NH3 would be produced if you started out with 56 grams of nitrogen gas and 10 grams of hydrogen gas?
