Chapter 1, Problem 1.5E

The dose of a chemotherapeutic agent prescribed for a patient who weighs 150 lbs. and is 5’1” tall is 1750 mg/m2/dose given once. The body surface area of the patient is ____ m2, and each dose is equivalent to _______  g.   2.20 lb = 1 kg 1 lb = 454 g

What is the density of gold 19.3 g/cm3 in kg/m3?

Heptane and water do not mix, and heptane has a lower density (0.684 g/mL) than water (1.00 g/mL). A 100-mL graduated cylinder with an inside diameter of  3.44  cm contains 31.0  g of heptane and 33.5 g of water. What is the combined height of the two liquid layers in the cylinder?  The volume of a cylinder is π r2h, where r is the radius and h is the height.

Heptane and water do not mix, and heptane has a lower density (0.684 g/mL) than water (1.00 g/mL). A 100-mL graduated cylinder with an inside diameter of  3.00  cm contains 29.7  g of heptane and 36.4 g of water. What is the combined height of the two liquid layers in the cylinder in cm?  The volume of a cylinder is π r2h, where r is the radius and h is the height.

A pure diamond has a density of 3.52 g/cm3. How do I convert this into kg/dm^3?

Some bottles of colorless liquids were being labeled when the technicians accidentally mixed them up and lost track of their contents. A 15.0-mL sample withdrawn from one bottle weighed 22.3 g. The technicians knew that the liquid was either acetone, benzene, chloroform, or carbon tetrachloride (which have densities of 0.792 g/cm3, 0.899 g/cm3, 1.489 g/cm3, and 1.595 g/cm3, respectively). What was the identity of the liquid?

The active ingredient of aspirin tablets is acetylsalicylic acid, which, has a density of 1.4 g/cm3. In a lab class, a student used paper chromatography to isolate another common ingredient of headache remedies. The isolated sample had a mass of 0.384 g and a volume of 0.32 cm3. Given the data in the following table, what was the other ingredient in the headache remedy? Density Values for Potential Headache Remedies Compound Density (g/cm3) White table sugar 0.70 Caffeine 1.2 Acetylsalicylic acid 1.4 Sodium chloride 2.2

You can figure out whether a substance floats or sinks if you know its density and the density of the liquid. In which of the liquids listed below will high-density polyethylene (HDPE) float? HDPE, a common plastic, has a density of 0.97 g/mL. It does not dissolve in any of these liquids.

1.69 The “Western Stone” in Jerusalem is one of the largest stone building blocks ever to have been used. It has a mass of 517 metric tons and measures 13.6 m long, 3.00 m high and 3.30 m wide. What is the density of this rock in g/cm3? (1 metric ton 1000 kg)
