Question 3: The Calibration of a 10 mL Volumetric Pipette. A 10 mL volumetric pipette is calibrated at 20.0°C. In the experiment the mass of the water dispensed is measured 10 times (a) What is the average mass dispensed by the pipette? (b) What is the standard deviation of the mass dispensed? (c) Given that the density of water is 0.998203 g/mL at 20.00C calculate the volume dispense in each trial (d) Calculate the average volume dispensed by the pipette (e) Calculate the standard deviation of the volume dispensed by the pipette (f) calculate the % error incurred by using this pipette (hint it is supposed to dispense 10.00 mL) Trial # 1 2 3 4 5 6 7 8 9 10 Average Here ---> Standard Deviation Here -- % Error --> mass of water in grams 9.9604 9.9645 9.9632 9.9715 9.9683 9.9741 9.9682 9.9617 9.9641 9.6544 0.089532 0.2831 Volume of water dispensed (mL)
