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.

A variation of the indicator-dilution method (see preceding problem) is used to measure total blood volume. A known amount of a tracer is injected into the bloodstream and disperses uniformly throughout the circulatory system. A blood sample is then withdrawn, the tracer concentration in the sample is measured, and the measured concentration [which equals (tracer injected)/(total blood volume) if no tracer is lost through blood vessel walls] is used to determine the total blood volume.In one such experiment, 0.60 cm3 of a solution containing 5.00 mg/L of a dye is injected into an artery of a grown man. About 10 minutes later, after the tracer has had time to distribute itself uniformly throughout the bloodstream, a blood sample is withdrawn and placed in the sample chamber of a spectrophotometer. A beam of light passes through the chamber, and the spectrophotometer measures the intensity of the transmitted beam and displays the value of the solution absorbance (a quantity that…

50 mg of granular salt is briefly stirred into a glass container of 1/5 liter volume filled with water. After briefly mixing, some salt is still seen at the bottom of the class. The visible salt is filtered from the water, weighed and determined to have a mass of 20 mg. What is the dissolved phase concentration of salt remaining in the water? Provide your answer to the nearest whole number in units of mg/l.
