Question

I am confused . I think it is the graduated cylinder is better because have more units to measure the volume . IIl. DETERMINATION OF THE DENSITY OF WATER 1. Weigh a clean, dry 150 ml beaker on a top loading balance and record the mass to the nearest.01g in data 2. Transfer some deionized water into a 2s0 mL clean beaker (about half full beaker). tables 3A, 3B and 4.l 3. Using a transfer pipette, carefully measure 10.00 mL of deionized water out of the 250 mL beaker. 4. Transfer the 10.00 mL of deionized water into the pre-weighed 150 ml beaker 5. Weigh the 150 mL beaker plus the 10.00 mL of water to the nearest 0.01 g and record the mass in data table 3A. 6. Calculate the density of water to the correct number of significant figures Procedure B 1. Measure 25.0 mL of deionized water with a 50 mL graduated cylinder 2. Dry the 150 mL beaker and transfer 25.0 mL of deionized water to the beaker 3. Weigh the 150 mL beaker plus the 25.0 mL of water to the nearest 0.01 g and record the mass in data table 3B. 4. Calculate the density of water to the correct number of significant figures. 191 Page
