Explain the density of a liquid is to be found by weighing a dry 100-mLvolumetric flask, then filling it with the liquid and weighing it again. The volumetric flask has a mass of about 70g and an uncertainty of ± 0.1 mL the liquid has a density that is extremely nearly 1g/mL. Four balances are available, reproducible to 0.1g, 0.01g, 0.001g, and 0.0001g, respectively. Explain which balance(s) will give the maximum precision possible for the density measurement? Is there an advantage to utilizing the 0.0001-gbalance for this work? Explain.
