Aqueous Solution Problem
« on: August 19, 2015, 03:28:33 PM »
"   A Aqueous solution of K3PO4 5% in Mass has a density of 1,043g/ml.
a)   What is the Molar Concentration, Mole Fraction and Molal Concentration of the solution?
b)   When 80ml of this solution are mixed with 70ml of a solution of K2SO4 0,750mole/L, what is the final Molar concentration of the Ions?
c)   What is the Volume needed of a Solution of CaCl2 0,900mole/L to completely precipitate Ca3(PO4)2 with 150ml of this K3PO4 Solution?"

All well and good. Why not write it up to help others that may come this way in the future looking for help on this or similar problems?
