1. EXPERIMENT 3 DENSITY DETERMINATIONS

2. EXPERIMENT 3 DENSITY OF A REGULAR SHAPE SOLID DENSITY OF AN IRREGULAR SHAPE SOLID DENSITY OF WATER DENSITY OF AN UNKNOWN LIQUID BASED ON DENSITY, IDENTIFY THE REGULAR AND IRREGULAR SOLIDS AND THE UNKNOWN LIQUID

4. EXPERIMENTAL d = m/V MEASURE m AND V THEORETICAL HANDBOOK AND APPENDIX H

5. REGULAR SHAPED SOLID ONE OF THE FOLLOWING CYLINDERS: ZINC (Zn)TIN (Sn) LEAD (Pb)COPPER (Cu) ALUMINUM (Al) VOLUME OF A CYLINDER: V =  r 2 L =  (d/2) 2 L SELECT ONE, RECORD LETTER ON END, DETERMINE ITS DENSITY AND IDENTIFY THE METAL

6. IRREGULAR SHAPED SOLID ONE OF THE FOLLOWING METALS: –COPPER (Cu) –LEAD (Pb) –ALUMINUM (Al) USE 100 ml GRADUATED CYLINDER SELECT ONE, RECORD ITS LETTER, DETERMINE ITS DENSITY, IDENTIFY METAL BASED ON DENSITY

7. DENSITY OF WATER USE 25 ml GRADUATED CYLINDER DETERMINE MASS OF DRY & CLEAN GRADUATED CYLINDER FILL TO A LEVEL BETWEEN 20 AND 25 ml WITH DISTILLED WATER (RECORD EXACT LEVEL) DETERMINE MASS OF GRADUATED CYLINDER AND WATER DETERMINE DENSITY OF WATER

8. DENSITY OF UNKNOWN LIQUID DETERMINE DENSITY USING SAME PROCEDURE AS FOR DISTILLED WATER UNKNOWN IS ONE OF THE FOLLOWING: –HEXANE  0.660 g / mL –METHANOL  0.791 g / mL –ETHYL ACETATE  0.900 g / mL BASED ON DENSITY, IDENTIFY LIQUID

9. HOW TO READ A CALIPER? THEORETICAL DENSITY ORDER OF EXPERIMENTS

10. RETURN CALIPERS & METAL CYLINDERS TO REAGENT BENCH RETURN METAL PELLETS TO APPROPRIATE WASTE BEAKER UNKNOWN LIQUID CAN GO DOWN THE DRAIN

11. EXPERIMENT 3 QUESTIONS? IT IS TIME TO GO TO WORK!
