In the metric sys- sities of solids and liquids are usually expressed as grams per cubic centimeter grams per mililiter (g/ml.). The densities of gases are usually stated as grams er liter (g/L) TABLE 2.8 gives the densities of some common substances.

SAMPLE PROBLEM 2.11 Calculating Density TRY IT FIRST tein (HDL) is a type of cholesterol, sometimes called "good choles- ured in a routine blood test. If a 0.258-g sample of HDL has a volume 0.215 mL what is the densitraser i, of the HDL sample?

A graduated cylinder which has been filled with 20.00 mL of water. A solid object is added to the graduated cylinder and the water level rises to the 26.40 mL. Calculate the mass (in grams) of the solid object which has a density of 3.26 g/mL.

A textbook is 27 cm long, 21 cm wide, and 4.4 cm thick. What is the volume in(a) cubic centimeters?(b) liters?(c) cubic inches?

A tortoise ambles along at 64.6 mm/s. What is this in miles/hr ? Use 1 = 1.609 km in your calculations.

The density of mercury, the only metal that is a liquid at room temperature is 13.6 g/mal. Calculate the mass of 5.50 mL of the liquid.

The following densities resulted from a student's measurements. What is the mean of their densities? Include units in your answer. Density 1 = 8.51 g/mL Density 2 = 9.97 g/mL Density 3 = 9.07 g/mL

Liquid Tylenol has 325 milligrams of acetaminophen per 12.5 milliliters of liquid medicine (a fact that would be commonly abbreviated as 325 mg/ 12.5 ml). It means that if you could pour Liquid Tylenol into a 12.5 milliliter cup and separate all of the ingredients, you would find that it contains 325 milligrams of acetaminophen (the active ingredient that relieves pain) along with some inactive ingredients like flavorings. The doctor orders 260 milligrams of acetaminophen for a patient. If the patient takes the medicine in the form of Liquid Tylenol, how many milliliters of Liquid Tylenol would he need to take to get the prescribed amount of acetaminophen?

The density of a substance is 1.5 grams per milliliter. What is the mass of 0.35 liters of the substance in grams?

When converting between metric units, use the prefixes to help you determine the magnitude of a value. The prefix kk indicates kilo, 1000. Therefore 1000 gg = 1 kgkg. A 25.0 kgkg iron weightlifting plate has a volume of 3180 cm3cm3 . What is the density of the iron plate in g/cm3g/cm3?

A Chemistry student had a cold and took 2.3 teaspoons (tsp) of cough syrup. If the syrup had a density of 0.950 g/mL and there is 6.0 mL in 1 tsp, what was the mass, in grams, of the cough syrup? Provide numerical values in standard notation (not scientific notation) not including units.
