UNIT 1: Lesson 1
As you read text pp 13-15, highlight, underline, star content, bracket information; write notes in the
margin; review and work any sample problems that will help you answer the following questions over
the content covered on these pages:
1. What is density? Amount of MASS in a given amount of VOLUME
2. What scientific statement can be made about a substance’s density? No matter how much of the
substance is measured (half, a small piece…); its density will be the same as the original
amount. (e.g. gold [Au] brick = 19.3 g/cm3; ¼ of that gold brick = 19.3 g/cm3)
3. What is the formula for density? Density = mass divided by volume [D = m/v]
4. What is the label for density? The mass unit of measurement “per” the volume unit of
measurement.
5. Give an example of a solid substance’s density and a liquid substance’s density?
Solid substance = g/cm3; Liquid substance density = g/mL
6. Given the following data of a substance [12 mL and 144 g], which measurement represents the
mass and how did you determine it? 144 g = mass because of the “gram” label
7. What is the density of the obsidian rock on Pg 14? [Reference: Sample Problem pg 14]
D=2.6 g/cm3
8. State the formula for finding the mass of a substance if its density and volume are given?
mass = Density times volume; [m = D (v)]
9. What do you need to know about the units of measurement for mL and cm3 to work the sample
problems on pg 15? That both “mL” and “cm3” are equivalent units of measurement
10. What is the mass of the rhyolite rock in the second sample problem on pg 15? m=24.7 g
