Could someone please help me with this problem? I need to know the answer, so that I can make sure I solve it correctly once I try to do it on my own... But knowing the process is what's most important. So, I would appreciate if someone gave me the answer and walked me through how they got there. I am most confused about theoretical yields, if that makes any difference! :) Thanks in advance.
