Calculate the molarity of Na2C204 solution prepared by dissolving 1.2222 grams of pure Na2C204 in enough water to make 500.00 mL of solution.

  1. Hurrrdurrbeedooda

    Get the moles.
    n = m/MM
    n = 1.222grams / (Na2C2O4 Molar Mass)

    Molarity = mole / volume
    = [1.222g / (Na2C2O4 Molar Mass)]/0.500 L.
