The amount of matter in an object is called (a) .
What do you call the space that is occupied by an object?
mass
weight
volume
density
What is Density?
The amount of matter in an object
The ability of being porous
The ability of decaying
The amount of particles of a matter in a space occupied by the object.
What is the density of water?
.92 g/cm3
1 g/cm3
2.70 g/cm3
2.92 g/cm3
What is the formula to find density?
Density = mass - volume
Density = mass + volume
Density = mass / volume
Density = mass x volume
