Question
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.
