An instrument used to detect metals in drinking water can detect as little as 1 ug of mercury in 1 L of water. Mercury is a toxic metal; it accumulates in the body and is responsible for the deterioration of brain cells. Calculate the number of mercury atoms you would consume if you drank 1 L of water that contained only 1 ug of mercury. ( The mass od one mercury atom is 3.3 x 10^-22 g.)
