I am still waiting on 2 students to take the quiz from last week so I can't hand back those quizzes yet. You can stop by and look at your quiz however.

No, it is a slow go. Each report takes about 15 - 20 minutes and with other grading it will be a few more days. It might even be next Monday. I will try to post a distribution of grades in the morning for those that I have graded.

Answer to Pre-lab #2

y = 3050 x -.005400 with y = Abs and x = concentration

The R2 value is .9994

The closer R2 is to 1, the better straight line it is and the better fit to Beer's Law

The unknown concentration is 1.74 E-4 M
