Suppose that ammonia (a monoprotic base), applied to a field as a fertilizer, is washed into a farm pond containing 3.0 × 106 L of water. If the pH of this pond is found to be 9.81, what volume of liquid ammonia found its way into the pond? [Given: Kb(NH3) = 1.8 × 10-5; the density of liquid ammonia is 0.771 g/cm3]
