1) Weigh a test tube and record the weight with correct significant figures. Use a weigh boat to hold the test tube. Make sure to zero the scale after putting the weigh boat. 2) Measure 2 mL of water with a 10 mL graduated cylinder (Note significant figures obtained from the cylinder. What is the real volume with significant figures (report a measurement with two digits decimal place)? Add to the 1st test tube, weigh, and record the weight. 3) Weigh a 2nd test tube. Measure 2.0 mL baby oil with a 10.0 mL graduated cylinder, add to test tube, weigh, and record the weight. 4) Add 1 drop of prepared cabbage dye solution to the water in the 1st test tube. 5) Combine the baby oil in the 2nd test tube with the 1st test tube by adding the water to the baby oil test tube. Does it float on top or sink? Record your results. 6) Weigh and record the mass of the heavy object. 7) Determine its volume by a volume displacement or length measurement. Record the volume with the correct number of significant figures. 8) Weigh the light object. 9) Determine its volume by a volume displacement or length measurement. Record the volume. If length measurement, volume measure may be by length x width x height cm Data: 40pts Water 1) Mass of test tube 1:....... 2) Mass of water + test tube 1: 3) Mass of water [2) - 1)]:. 4) Volume of water: Baby oil 5) Mass of test tube 2: 6) Mass of baby oil + test tube 2: 7) Mass of baby oil [6) - 5)]:. 8) Volume of baby oil: ... 9) Observation of baby oil + water:
