Solution Dilution - Example 4

-- how much stock solution should you start with if you want 2.5 L of a 0.1 M KCl solution and the stock solution is 5.5 M?

-- formula: M1 x V1 = M2 x V2

-- M1 is 5.5 M

-- V1 is unknown

-- M2 is 0.1 M

-- V2 is 2.5 L

     5.5 x V1 = (0.1)(2.5)

     5.5 x V1 = 0.25

     V1 = 0.04545

-- you would dilute 0.045 L of the stock solution to 2.5 L
