2. Density of pieces of metal (copper) Some metal pieces (copper) provided are weighed on a balance (about 60g) and the exact weight in gram recorded in Table 2, under mass (g) in column 2, Rep #1. A 100-ml cylinder is filled to about 50 ml of water and exact volume in ml is recorded under the V₁ column, Rep #1. The weighed metal pieces are immersed into the water in the cylinder. The new volume of water in ml is recorded under the V₂ column in the data Table 2, which is the volume after immersing the metal pieces. The change in volume of water (V₂ - V₁) is calculated and recorded (This is the actual volume in ml of the metal pieces). This procedure is repeated in the same manner to complete Rep #2 and #3. Assignment The theoretical data generated following the procedure outlined above are given in Table 2 below. From these data, calculate the density and % error values and enter in the last column blank spaces. Density of metal pieces is calculated by dividing mass of metal by change in volume, (g/ml) The mean density values are calculated by adding the three replications and dividing by 3. The error % as compared to the standard density of copper, which is 8.5g/ml, is calculated using the formula given under density of water measurement. Table 2.
