Practitioners of the branch of alternative medicine known as homeopathy claim that very dilute solutions of substances can have an affect. Is this claim plausible? To explore this question, suppose that you prepare a solution of an active substance X, with a molarity of 0.10 mol per liter. Then you dilute 10. ml of that solution by doubling the volume, doubling it again, and so on, for 90 doublings in all. How many molecules of X will be present in 10. ml of the final solution?
