Mass and Volume Shape and Length Shape and Size Color and texture
A student is given an unknown substance and has to calculate the density. Which physical properties must first be determined? B Mass and Volume Shape and Length Shape and Size Color and texture

All three cylinders pictured above have the same volume. Which statement best describes the relationship between the densities of the cylinders and their contents? 6.6B Cylinder R is denser than Cylinders S and T. Cylinder T is denser than Cylinder R but less dense than Cylinder S. Cylinder S is less dense that Cylinder T and denser than Cylinder R. Cylinders R and T have the same density.

Salad oil floats on water. Water has a density of 1. 0 g/cm
Salad oil floats on water. Water has a density of 1.0 g/cm . What can you say about the density of the salad oil? B There is insufficient information to say anything about the density. It is 1 g/cm3 It is less than 1 g/cm3 It is greater than 1 g/cm3

A student has an unknown mineral. The mass is 33
A student has an unknown mineral. The mass is 33.6 grams and the volume is 8 cm3. Based on the table above, what is the name of the mineral? B Galena Magnetite Copper Rutile 33.6 grams 8 cm3

Which of the following tables correctly matches each physical property to the tool that would best measure it? B

3 x 3 x3= What is the volume of the cube? 6.6B 3 cm3 9 cm3 27 cm3
What is the volume of the cube? B 3 cm3 9 cm3 27 cm3 30 cm3 3 x 3 x3=

Final – initial= volume
The diagram shows a graduated cylinder before and after an iron rod is placed in the cylinder. What is the volume of the iron rod? B 7 mL 11 mL 15 mL 18 mL Final – initial= volume 30-23=

8.5-1.0= What is the length of the metal rod below? 6.6B 7.0 cm 7.5 cm
7.0 cm 7.5 cm 8.0 cm 8.5 cm =

A student combines Liquid A and Liquid B in a beaker
A student combines Liquid A and Liquid B in a beaker. The student stirs the liquids and observes that the liquids do not form a solution. Further observation reveals the Liquid A rises to the surface and settles on top of Liquid B. What can the student conclude about Liquid A? B Liquid A is denser than Liquid B. Liquid A is less dense than Liquid B. Liquid A and Liquid B have the same density. Liquid A must be water.

What is the density of an unknown substance that has a mass of 30 g and a volume of 10 mL? 6.6B
1 g/mL 3 g/mL 30 g/mL 300 g/mL 30 grams 10 mL

Final – initial= volume
A student places a 15 gram piece of quartz in a graduated cylinder. The water level rises from 30 mL to 35 mL. What is the density of the quartz? B 3 g/mL 5 g/mL 20 g/mL 80 g/mL 15 grams __mL Final – initial= volume 35-30=5mL

A student finds a 300 gram object that has a volume of 30 cm3. Which object has the same density as the object the student found in the table above? B Object Q Object R Object S Object T 300 grams 30cm3

The diagram shows the mass of a cube in grams of metal measuring 3 cm on each side. What is the density of the metal? B 0.2 g/cm3 5 g/cm3 27 g/cm3 45 g/cm3 grams 27 cm3 =

What is the density of unknown 1? What is the substance? B 4.5 g/cm3; titanium 2.7 g/cm3; aluminum 19.3 g/cm3; gold 2.2 g/cm3; table salt 99.9 grams 22.2 cm3
