We’re being asked to determine the molarity of mercury (Hg) in a 0.68-ppb solution. Let’s first define ppb.
• 1 ppb means 1 part of solute for every 109 parts of the solution
The level of mercury in a stream was suspected to be above the minimum considered safe (1 part per billion by weight). An analysis indicated that the concentration was 0.68 parts per billion. Assume a density of 1.0 g/mL and calculate the molarity of mercury in the stream.
