19. The data table below shows the masses and volumes of three objects (A, B, and C).
The formula for calculating an object’s density is:
Density = Mass/Volume.
Which object is the densest?
1. 2. 3. 4. 20. 1. 2. 3. 4. 21. A

All three objects have equal densities.
When two elements chemically react, the mass of the product is
equal to the mass of the lighter element
equal to the mass of the heavier element
equal to the sum of the masses of the two elements
greater than the sum of the masses of the two elements
Mass is a measure of
1. the amount of matter 3. the density of matter
2. the weight of matter 4. the buoyancy of matter
