DWU #2- A compound contains 83.12% sodium and 16.18 % nitrogen by mass. What is the empirical formula?
I checked the homework and went over it before I gave the homework quiz. Most of the period was spent going over the lab calculations. At the very end of the period we did the coloring for the mole day decorations. We will finish the calculations on Thursday (in Mrs. Messenger's room).
HW: p. 189 #19abc, 21ace, 23bcd, 25bde and finish lab calculations and conclusion.
