a. mass only

b. volume only

c. density only

d. mass and volume

e. volume and density

Which is the correct equation for calculating density? (a) Density = Mass/Volume (b) Density = Mass/Weight (c) Density = Volume/Mass (d) Density = Volume/Weight

Explain how gas density is related to molar mass and temperature.

Calculating Density The density of an object is the object's mass divided by its volume. To find the density of an object, use the formula below.

Density $=\frac{\text { mass }}{\text { volume }}$

Predict - Suppose a mineral has the same mass as the quartz in Question $1$ but a greater volume. How would its density compare to the quartz in Question $1$ ?

A large piece of jewelry has a mass of $132.6 \mathrm{~g}$. A graduated cylinder initially contains $48.6 \mathrm{~mL}$ water. When the jewelry is submerged in the graduated cylinder, the total volume increases to $61.2 \mathrm{~mL}$. (a) Determine the density of this piece of jewelry. (b) Assuming that the jewelry is made from only one substance, what substance is it likely to be? Explain.

Indicate whether each of the following can be determined exactly or must be measured with some degree of uncertainty: (a) the number of seconds in an hour (b) the number of pages in this book (c) the number of grams in your weight (d) the number of grams in 3 kilograms (e) the volume of water you drink in one day (f) the distance from San Francisco to Kansas City

How many significant figures are contained in each of the following measurements? (a) 53 cm (b) $2.05 \times 10^{8} \mathrm{m}$ (c) 86,002 J (d) $9.740 \times 10^{4} \mathrm{m} / \mathrm{s}$ (e) 10.0613 $m^3$ (f) 0.17 g/mL (g) 0.88400 s

Is a meter about an inch, a foot, a yard, or a mile?

Indicate the SI base units or derived units that are appropriate for the following measurements: (a) the length of a marathon race (26 miles 385 yards) (b) the mass of an automobile (c) the volume of a swimming pool (d) the speed of an airplane (e) the density of gold (f) the area of a football field (g) the maximum temperature at the South Pole on April 1, 1913

The density (d) of a substance is an intensive property that is defined as the ratio of its mass (m) to its volume
(V). density $=\frac{\text { mass }}{\text { volume }} \quad d=\frac{m}{V}$ Considering that mass and volume are both extensive properties, explain why their ratio, density, is intensive.

Identify the following properties as either extensive or intensive. (a) volume (b) temperature (c) humidity (d) heat (e) boiling point
