The following data were obtained from the calibration of an air-displacement pipette by repetitive drawing 1000.0 microliters of pure water at 4.00 °C using this pipette and weighing them on an analytical balance, which gave the following readings, respectively: 1.003, 1.000, 1.005, 1.007 g. How many measurements would have to be averaged to obtain an S/N of 1000? Type your numeric answer and submit
