- What is the smallest mass that we can measure on an analytical balance that has a tolerance of ±0.1 mg, if the relative error must be less than 0.1%?In order to find the density of a solution of unknown density, 10 mL of solution was drawn into a clean and dry beaker three times with a pipette and weighed and the weighing results were found to be 65.1452 g, 64.9982 g, 65.1027 g. Calculate the density of the solution and the standard deviation of the measurements, since the empty weight of the beaker is 52.2461 g.In an experiment a student used a 50 mL volumetric flask to prepare her copper solution but in calculations she used 100 mL as the sample volume. What effect will this error have on the final result? Will the calculated result be high of low?
