Mercury can be toxic but its compounds (indeed, the metal itself) have many useful applications. Some examples include: tooth fillings (as an alloy with silver, copper and tin) and the industrial production of chlorine. However, some compounds must be removed from waste water due to their toxic properties such as mercury (II) nitrate. One way to remove this compound involves reacting the wastewater with sodium sulphide solution to produce a double displacement reaction. In order to test the effectiveness of this procedure, 0.020 L of 0.10 M mercury (II) nitrate reacts with 0.050 L of 0.010 M sodium sulfide. How many grams of mercury (II) sulphide form?
