Bucks McGee, after being poisoned, is currently being treated in the hospital with an antidote- the chemical Fe(CN)18. The compound is so intensely coloured that even a small amount of it makes for a black or dark blue suspension. 2022-02-0. Given that this antidote has never before been administered at the hospital, none of the doctors or nurses have experience with it. There is one very old bottle of Fe>(CN)18 pills in the medicine store-room, but the label is worn and the units are in the old, archaic British Apothecaries' system which has unusual units like drachms, scruples, grains, and mites: 453.6 grams (g) = 1 pound (Ib) = 12 ounces (3) = 96 drachms (3) = 288 scruples (3) = 5760 grains (gr) = 115200 mites (m) ruu useu tnis antidote long ugu at dnother hospital, and who seemed to remember that they used to make 0.025 M solutions of this compound in ethanol and give 45 mL of the solution three times daily. What critical information is missing from the worn label? How many pills…

A note on the door of the cabinet says the cabinet is used to store bottles of pentane, dimethyl sulfoxide, acetone, methyl acetate, and chloroform. The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection of Material Safety Data Sheets (MSDS), the chemist finds the following information: liquid density 0.63 mL pentane db dimethyl sulfoxide 1.1 0.79 acetone 0.93 mL methyl acetate 1.5 chloroform 3 Next, the chemist measures the volume of the unknown liquid as 1797.…
