Dissolve 0.977 g of KH2PO4 into a 500.0 mL volumetric flask. Transfer the solution from the 500.0 mL flask into a buret and transfer 3.00 mL of the solution into a 250.0 mL flask and dilute to the mark.. Calculate the exact concentration of P in ppm in the 250 mL flask. Report your answer to 3 decimal places. MM P = 30.9737 g/mol MM KH2PO4 = 136.0855 g/mol
