A solution of phosphoric acid was made by dissolving 10.0 g H3PO4 in 100.0 mL water. The resulting volume was 104 mL. What is the density, mole fraction, molarity, and molality of the solution? Assume water has a density of 1.00 g/cm3.
Calculate the molality, molarity and mol fraction of a 25.4% (by mass) aqueous solution of phosphoric acid (H3PO4).
