Pipets used for transfer of samples of solutions are always rinsed with a small portion of the solution to be dispensed with the pipet before the actual sample is taken. Calculate the percentage error likely arise in an experiment if 1-mL, 5-mL, and 10-ml pipets are used for transfer and each pipet contains 5 drops of liquid adhering to the inside of the barrel. Assume a volume of about 0.05mL per drop.
