I need help! I have an absolutely terrible analytical chemistry teacher, and I don't understand a thing. I am feeling really discouraged. Can someone please give me a detailed run down of how to write mass balance equations for known and unknown concentrations. THANKS!!

Mass balance has to do with how much of one thing is there when compared to another. Keep in mind that if one of the constituents reacts you need to remember that it also must be considered.

Very off target, but, popjinx. You go to the Univ. Of Pittsburgh too. Who is your Analytical Chem Prof? You say you tutor O-Chem. Are you member of the UTU program with Dr. Bandik? I'm in the general chem UTU group with Dr. Golde. I probably pass you in Chevron without knowing it.

My professor for analytical is Shigeru Amemiya (do not ever take him for anything. you will regret it big time). I don't tutor organic chem for the university. I actually help wash glass ware and set up chemicals before labs as a lab assistant. However, I do tutor organic chem outside of the University. So, if you do need help with something, then you can feel free to contact me.
