7. Ammonium sulfate is widely considered to be the most important fertilizer in the world. It can be made according to the following reaction:
2 NH3(aq)+ 1 H2(SO4)(aq) = 1(NH4)2(SO4)(aq)
How many grams of ammonium sulfate could be theoretically made if 250.0 mL of a 4.00M solution of
NH3 are reacted with 500.0 mL of a 2.00M solution of sulfuric acid? Which reactant is your limiting
reactant?
If 45.5 grams of ammonium sulfate are actually made, what is your percent yield?
