Express the concentration of a 0.0660 M aqueous solution of fluoride, F, in mass percentage and in parts per million (ppm). Assume the density of the solution is 1.00 g/mL. mass percentage: ppm: % ppm

An aqueous Na;PO, solution is made using 42.3 g of Na:PO, diluted to a total solution volume of 2.00 L. 163.94 g NazPO4) (molar mass 1 mole Na3P04 a) In one calculation string, show the calculation for determining the molarity of the sodium phosphate solution. b) In one calculation string, show the calculation for determining the mass percent of the sodium phosphate solution from the molarity you determined in part a. c) Show the necessary calculations for determining the molality of sodium phosphate solution from the molarity you determined in part a. These calculations should be as condensed as possible, but don't need to be in one string. Assume a density of 1.08 g/mL for the solution.

A solution is made by dissolving 25 g of NaCl in enough water to make 1.00 L of solution. Assume that the density is 1.00 g/cm^3.
