 5/8/2018 Handout you got today for Mass% & Molarity Lab. Attach a separate sheet of paper when you calculate all other groups' calculations. Wheh your calculations are
different from what other groups posted, circle your answer to show it is different.
Handout with calculations and data for your solutions is page 1 of your lab. Your calculations for all other groups is stapled to your handout.
