A sample of an ethanol-water solution has a volume of 54.4 cm^3 and a mass of 49.9 g. What is the percentage of ethanol (by mass) in the solution? (Assume that there is no change in volume when the pure compounds are mixed.) The density of ethanol is 0.789 g/cm^3 and that of water is 0.998 g/cm^3.

A student pipetted 10 mL of a sample solution into a 250 mL volumetric flask and diluted it to the mark with distilled water. The student then, pipetted 10 mL of this new solution into a 50.00 mL volumetric flask and diluted it to the mark with water. What is the dilution factor of the final solution?   25X   100X   125X   5X   50X

Heparin is available in a 10 mL vial containing 2500 units/mL.  A heparin infusion is prepared by adding 7.5 mL of the heparin stock solution to a final volume of 500 mL of Dextrose 5% in Water. What is the infusion rate (mL/hour) required to deliver a dose of 18 units/kg/hour to a patient who is 6’0” tall and weighs 154 lbs?

Does it make a difference if you use a volumetric flask vs a beaker vs a graduated cylinder to make a solution?

The concentration of PSA (prostate-specific antigen) in the blood is sometimes used as a screening test for possible prostate cancer in men. The value is normally reported as the number of nanograms of PSA per milliliter of blood. A PSA concentration of 1.7 ng/mL1.7 ng/mL is considered low. Express that value in terms of the units shown.   PSA=         g/L PSA=        kg/m3 PSA=        mg/L
