calculate the final concentration of the solution in each of the following: a)water added to 10.0 mL of a 3.50 M KNO3 solution gives a volume of .250 L. b)a 5.00-mL sample of a 18.0 M sucrose solution is diluted with water to 100. mL. c)water is added to .250 L of a 12.0 M KBr solution to give a volume of 1.00 L.
