Aqueous ammonia is typically sold by chemical supply houses as the saturated solution, which has a concentration of 14.5mol/L. What volume of NH3 at STP is required to prepare 100. mL of concentrated ammonia solution?
14.5 M = 14.5 mols/L = 1.45 mols/100 mL.
1.45 mols NH3 x molar mass NH3 = grams NH3.
