Laughing Gas, N2O, is made by the careful decomposition of ammonium nitrate
NH4NO3 (s) = N20 (g) + 2H20 (g)
How many grams of N2O can you obtain?
How many dm3 of stream would also be produced?
Not interested in the name of your high school. It is important that you say chemistry though so you do not get a cranky old physicist looking at your question.
There is no way to tell how much comes out without knowing how much went in.
