Chapter 01: Essential Ideas
1. A 0.150 kg metallic block measures 25.0 mm in length, 43.0 mm in width, and 19 .0
mm in height. What is the density of the metallic block in g/cm3? (Outcome # 3)
(DOK 2)
A. 7.34 x 10-6 g/cm3
B. 7.34 x 10-3 g/cm3
C. 7.34 g/cm3*
2. An object with a mass of 0.255 kg and density of 2.89 g/cm3 measures 34 mm in
length and 46 mm in width. What is the height of the object? (Outcome # 3) (DOK
3)
A. 5.6 cm*
B. 5.6 x 10-2 cm
C. 7.2 x 10-4 cm
3. How would you determine the density of an irregular object? (Outcome # 3) (DOK 3)
A. It would be impossible to determine the mass of the object without
more information.
B. D = m/v, so measure the mass of the object using a balance. Then to find volume,
Mmeasure the height, width, and length using an appro priate measuring tool.
, C. D = m/v, so measure the mass of the object using a balance. Then to find
volume, fill a graduated cylinder with a known amount of water and immerse
the object in the water. The amount of displaced water is the volume in cm3 or
mL.*
4. What is the base unit for length in the metric system? (Outcome # 6) (DOK 1)
A. m*
B. km
C. mm
5. What is the base unit for mass in the metric system? (Outcome # 6) (DOK 1)
A. kg
B. g*
C. mg
6. What is the base unit for volume in the metric system? (Outcome # 6) (DOK 1)
A. L*
B. mL
C. dL
7. It is important that scientists use units that are understood on a global level. These
units are referred to as SI units which stands for . (Outcome # 6) (DOK 1)
A. standard international units
