10:40 AM Fri Mar 3 Virtual Lab Expt. #3 Density and Specific Gravity 3. Density of metal rounds (steel) The mass in gram of three metal round (steel) provided is measured one at a time and data entered in Table 3, under column 2, Replications #1, #2, #3, respectively. Overflow-cup with a drain-nozzle is placed on a bench above the water sink and filled with water until excess water flows out through the nozzle and levels off. After the excess water stops dripping out of the overflow-cup, an empty beaker is held under the nozzle with one hand and the metal round, of which mass entered in Rep #1, is gently dropped in the water with the other hand; the metal will displace a fraction of the water and water flows out through the nozzle into the beaker. The content of the beaker is then poured into a small, graduated cylinder, and the volume is measured in ml and data recorded under volume of metal column. The experiment described for Rep #1 is repeated in the same manner for metal rounds 2,…
