1-A 10 mL pipet has graduation marks every 0.1 mL, therefore it can be read to 2 decimal places. When a liquid is drawn to the 10 mL mark, it should dispense 10.00 mL of liquid. 2-Suppose this pipet is calibrated by dispensing distilled water from the pipet at exactly the 10 mL mark into a preweighed dry flask. The dry flask weighs 20.5472 g empty, and 30.5733 g with the dispensed water (21 °C). If the density of the water is 0.997770 g mL-1 at this temperature, what is the actual volume delivered by the pipet? 2. When getting results, it is best to do more than one trial. The following volumes were obtained for the calibration of a 10 - mL pipet: 10.028415, 10.140035, 10.091111, and 10.012213 mL. Calculate the mean value, the standard deviation and then report your value.
