Ammonia (NH3) is a weak base that reacts with a strong acid to form the ammonium ion, NH4+. If 1.500 mL of a solution of an ammonia cleaner is titrated directly with 42.6 mL of 0.5000 M HCl, what is the concentration of the NH3 in solution? (Assume that the ammonia is the only solute that reacts with the acid.)
