3. LAB SETUP Groups of 4-5 ppl Use the blue/green cups – The top ridge is 400mL USE A WEIGHBOAT – NO chemicals directly on the scales!! Don’t forget your DAY 1 data Where to put them? – Per 1: By the “STATION 2” sign – Per 2: By the “STATION 4” sign HW: work on lab write up (thru results table)

4. MATERIALS PROCEDURES - HOW did you make up the 4 sol’ns? - WHAT are you doing with those sol’ns? RESULTS - Create your own data table CONCLUSION Answer the questions here

5. Double Check Your Math 400mL of a 0.5M NaCl solution: 0.5M = x mol = 0.2mol of NaCl 0.4L (0.2mol)(58.44g/mol) = 11.69g

6. DAY 2 Get your “Day 2” measurements – Clean up your mess – Rinse out cups and turn upside down to dry – Throw your carrots away Work on your lab write up
