Roviee Topics The concentrations of pollutants are often reported as parts per million (ppm). Parts per million of a solutions defined mass of solute ppm = x1 x 10 masa of aolution The U.S. Environmental Protection Agency (EPA) limit for barium in municipal drinking water is 2.0 ppm a. Calculate the maximum mass percentage of barium allowed in drinking water. Mass percentage = b. Calculate the molarity of a solution of barium that is 2.0 ppm.
