How many grams of NH3 form when 27.5L of H2 (measured at STP)react with N2 to form NH3 according to:
N2(g) + 3H2 (g) = 2NH3 (g)
Here is an example of a stoichiometry problem. Just follow the steps. To convert L H2 to moles, remember that 1 mole of a gas occupies 22.4 L at STP.
Post your work if you get stuck.
