Vocabulary: Density, Mass, Volume?

Mass:  mass is the amount of material in an object.  Mass is measured with a balance, usually in grams or kilograms

Volume: volume is the amount of space occupied by an object. Volume is measured using a graduated cylinder or  is determined by calculation using the dimensions of the object.   Volume is measured  in  cm3, m3, mL and L.

Density:  Density is a mass to volume ratio. Density can be used to identify a substance because every pure substance has a unique density value. Objects with smaller densities will float in liquids that have greater densities.

density- degree of consistency measured by the quantity of mass per unit volume.

mass- the quantity of matter which a body contains, as measured by its acceleration under a given force or by the force exerted on it by a gravitational field.

volume- the amount of space that a substance or object occupies, or that is enclosed within a container, especially when great.
