Cola contains phosphoric acid, H3PO4. In order to determine the concentration of phosphoric acid in 50mL of Cola, a precipitation reaction with excess silver nitrate was carried out. The product, silver phosphate, was dried and found to weigh 0.0576g. What is the concentration of phosphoric acid in the Cola.

  • Chemistry -

    mass Ag3PO4 = 0.0576 grams.
    moles Ag3PO4 = 0.0576 g/molar mass Ag3PO4.
    mols phosphate = ??
    Moles H3PO4 = ??
    grams H3PO4 = ??
    How do you want concentration calculated. g/mL is g/50 mL.
    M = moles/L.
