I have no idea. I thought there were 0.020 moles of the compound, not of the base form of the compound necessarily? Since I have given it a legitimate go and still cannot deduce the answer, could you please tell me how to solve this problem? If not I can just go ask my professor during his office hours later this week, but I would have to go during my lunch break from work so it would be more convenient to have the solution from you. I understand if that violates the forum policy, though. Either way, thank you for your help so far.
