Buffers in Medicine?

As a technician in a large pharmaceutical research firm, you need to produce 450 mL of 1M potassium phosphate solution of pH = 7.10. The pKa of H2PO4- is 7.21. You have 2L of 1 M KH2PO4 solution and 1.5L of 1M K2HPO4 solution, as well as a carboy of pure distilled H2O . How much 1 M KH2PO4 will you need to make this solution?
