*9. ssm The preparation of homeopathic “remedies" involves the repeated dilution of solutions containing an active ingredient such as arsenic trioxide (As2O;). Suppose one begins with 18.0 g of arsenic tri- oxide dissolved in water, and repeatedly dilutes the solution with pure wa- ter, each dilution reducing the amount of arsenic trioxide remaining in the solution by a factor of 100. Assuming perfect mixing at each dilution, what is the maximum number of dilutions one may perform so that at least one molecule of arsenic trioxide remains in the diluted solution? For compari- son, homeopathic “remedies" are commonly diluted 15 or even 30 times.
