Part A As a technician in a large pharmaceutical research firm, you need to produce 250. mL of a potassium dihydrogen phosphate buffer solution of pH = 6.93. The pK, of H;PO, is 7.21. You have the following supplies: 2.00 L of 1.00 M KH;PO, stock solutign, 1.50 L of 1.0o M K2HPO, stock solution, and a carboy of pure distilled H,O. How much 1.00 M KH,PO, will you need to make this solution? (Assume additive volumes.) Express your answer to three significant digits with the appropriate units. > View Available Hint(s)
