Ammonium hydrogen phosphate, a common fertilizer, is made from reacting phosphoric acid with ammonia (NH3). If 10.00g of ammonia react, how many grams of fertilizer will be produced?

Answer 1

NH3 + H3PO4 ==> NH4H2PO4
mols NH3 = grams/molar mass
mols NH3 = mols NH4H2PO4 (from the 1:1 ratio in the balanced equation)
g NH4H2PO4 = mols NH4H2PO4 x molar mass NH4H2PO4
