6. Ammonia (NH) is a weak base that reacts with a strong acid to form the ammonium ion, NH, If 5.00 mL of a solution of an ammonia cleaner is titrated directly with 42.6 mL of 0.5000 M HCI, what is the concentration of the NH, in solution? (Assume that the ammonia is the only solute that reacts with the acid.)
