Mass and volume are two units used to measure objects. Mass is the amount of matter an object contains, while volume is how much space it takes up.
Mass is the measure of the amount of weight that is accommodated in an object or a matter. Volume is the quantify of a finite amount of area of a given end. The weight of the container with the liquid gives the mass of the liquid.
No matter what size sample of water you measure, the relationship between the mass and volume will always be the same. Because D=m/v, the density is the same for any amount of water.
