Answer:
Hey i am not in your class, but i took AP Chem in high school with AP Bio and i think i have your solution. The thing is when you look at Grains (a unit of measure that pharmacy's [pills] use) that can be converted into grams. Now once you got those grams you want to convert them to kilograms. From then Kilograms to Moles and Moles can then be converted into Molecules =) (remember moles = 6.24 X 10 ^ 23) =) Bye!!
