The mercury content of a stream was believed to be above the minimum considered safe—1 part per billion (ppb) by weight. An analysis indicated that the concentration was 0.68 parts per billion. What quantity of mercury ingrams was present in 15.0 L of the water, the density of which is 0.998 g/ml?  ( 1 ppb Hg = (1 ng Hg)/(1 g water) )
