This is the first time that I am taking a Chem class online and one thing I was noticing is that even if the answer is correct and my professors are good with the answers that are typed in for the pre-lab quiz it is marked as incorrect. I think this might be because different school and professors see that there is more than one way to write the answer out. I you could give examples of how answers for formulas should be answered that would help a lot.
