Using the data in your textbook calculate the concentrations

Using the data in your textbook calculate the concentrations of the molecular and ionic species and the pH in aqueous solution that has a formal composition of 0.2800 M KH2PO4 0.0600 M K2HPO4.What is the concentration of the molecular species H3PO4?What is the concentration of K in molarity?What is the concentration of OH-?What is the concentration of PO4-3 in molarity? (use Ka3=4.2×10-13)What is [HPO4-2]?What is [H2PO4-]?
