    K3PO4 + 3 AgNO3 → Ag3PO4(s) + 3 KNO3

    It's not clear to me what a particle of AgNO3 is. Supposing there are 2 particles in every formula unit of AgNO3:

    (17.89 x 10^11 particles) x (1 formula unit / 2 particles) / (6.022 x 10^23 formula units/mol) =

    1.485 × 10^-12 mol AgNO3

    (1.485 × 10^-12 mol AgNO3) x (1 mol K3PO4 / 3 mol AgNO3) x (212.2663 g K3PO4/mol) =

    1.051 × 10^-10 g K3PO4

    (1.485 × 10^-12 mol AgNO3) x (1 mol Ag3PO4 / 3 mol AgNO3) x (418.5760 g Ag3PO4/mol) =

    2.072 × 10^-10 g Ag3PO4
