Unformatted text preview: Let us make 55mL of solution (to allow for the fact that, as we shall see, well be using some of it). To make 55mL of 0.01M solution, ( 29 ( 29 ( 29 ( 29 stock mL x M mL M mL x 5 . 5 01 . 55 1 . = = Now, take the 0.01M solution as the new stock to make 55mL of 0.001M solution: ( 29 ( 29 ( 29 ( 29 stock M of mL x M mL M mL x 01 . 5 . 5 001 . 55 01 . = = As you see, we make 55mL of each more dilute solution, then use 5.5 mL of that, to make the next more dilute member of the set. There is a means to calculate the amounts needed exactly but this simplistic example helps to make the case....
