10:34 AM Fri Mar 3 Virtual Lab Expt. #3 Density and Specific Gravity Experimental Procedure Density of water A 100ml graduate cylinder is filled with water more than half and read the exact volume in ml is read to one decimal place, and record in Table 1, under the column designated volume of water (ml), Rep #1, third column. A 150ml beaker is tared (zero) on analytical balance. 1. The volume of water in the cylinder is transferred quantitatively into the beaker; mass in grams of water in the beaker is measured, and data record under mass of water (g), in the second column, Rep #1 The same procedure is repeated for Rep and #3, the mass and volume data recorded in the appropriate columns. Assignment The theoretical data generated for mass and volume of water are already given in Table 1 below. From these data, calculate the density and % error values, using the formulae given and enter values in the respective blank spaces (last column): The density of water (d) is calculated by…
