Explain what is the concentration of selenium in ppm

Reference no: EM13681713

The examined of well water reports that the concentration of Selenium (Se) in the water is 6.50 x 10-4 M. The drinking water standards on the EPA website as well as find out that water with concentrations of selenium abouve 0.05 ppm are considered unsafe. Explain what is the concentration of selenium in ppm in the well water? If necessary, Presume the density of the well water is 1.00 g/ml.
