- Hello, I was hoping for some help with the prelaboratory questions for Analytical Chemistry. I am pretty sure I got number one, but I was very confused about the "second endpoint" calculations and I am pretty sure I have calculated the percentage wrong. These are the equations we are given to work with and the questions are below. Thanks in advance!
