    10.78moles

    Step-by-step explanation:

    Avogadro's hypothesis gives us a background understanding that 1mole of any substance contains 6.02x10^23 atoms.

    Now, If 1 mole of K3PO4 contains 6.02x10^23 atoms,

    Then Xmol of K3PO4 will contain = 6.49x10^24 atoms i. e

    Xmol of K3PO4 = 6.49x10^24/6.02x10^23 = 10.78moles
