Submit

4. A chemical compound is always a molecule, but a molecule is not always a chemical compound.

True

False

5. Volume is

The amount of matter in an object

The amount of space an object occupies

Anything that takes up space and has mass

The same thing as density

6. The mass of an object is

The amount of space it occupies.

Anything that has mass and takes up space.

The amount of matter an object has.

Always bigger than its volume.

7. How do you find the density of an object if you know the volume and the mass?

Add the volume and the mass together

Divide the volume by the mass

Subtract the mass from the volume

Divide the mass by the volume

Located in the nucleus

Much smaller than protons or neutrons

Submit
