You have a 1mM stock solution of Arsenic to treat culture cells in a liquid medium. You need to treat your cells with Arsenic such that it has a final concentration of 5nM once it has been added to the cells. You are given 1mL of cells, and you can only add 2uL of your reagent to your cells. What concentration should you dilute the stock to so that you only have to add 2uL of Arsenic to your 1mL of cells in order to have a 5nM concentration of Arsenic?
