A boric acid stock solution was prepared by dissolving 19 g boric acid in a small amount of purified water USP and then adding sufficient volume of purified water USP to make up the volume to 1000 ml. Calculate the volume of this solution needed to prepare 25 ml of 0.95% boric acid solution in purified water. A solution of sodium chloride contains 77 mEq/L. Calculate its osmolar strength in terms of milliosmoles per liter. Assume complete dissociation.
