It is common in laboratories to make concentrated "stock solutions" that may be used to prepare "working solutions" of any desired concentration. You are asked to dilute a stock of NaCl with a concentration of 0.5M.

a) Develop a dilution scheme to show how you might prepare 250 mL of a solution of 20mM NaCl from the stock solution.

b) Draw a dilution scheme to show how you might prepare 100mL of a solution of 10mM NaCl from the stock solution.

c) Draw a dilution scheme to show how you might prepare 200mL of a solution of 0.1mM NaCl from the stock solution.
