Phosphate that is added to our drinking water forms a protective layer of lead phosphate on the inside of the pipes that distribute that water to our homes. The EPA maximum limit for lead in drinking water is 50ppb. Calculate the concentration of phosphate needed to keep the lead concentration below 39ppb. The Ksp of lead phosphate Pb3(PO4)2 is 1.6×10-32. Report your answer in ppb to the nearest whole number. Phosphate is 94.97 g/mole and lead is 207.2 g/mole.
