How could you define the density?
Density = mass of an object divided by the volume of that object. Its unit is mass per unit volume.
How does mass volume density and weight compare?
Mass is the amount of matter in an object, volume is the amount of space it occupies, and density is the mass of an object per unit volume. Weight is the force acting on an object due to gravity, and it is dependent on the mass and the acceleration due to gravity. They are related but distinct properties of an object.
What is the measure of how much mass there is in a volume of a substance?
The measure of how much mass there is in a volume of a substance is known as the density. It is defined as the mass of a substance per unit volume. Density is often expressed in units such as grams per cubic centimeter (g/cm3) or kilograms per liter (kg/L).
How do specific volume and density differ?
Mass is the amount of substance an object, Volume is how much space an object displaces (or takes up) in space, and density is how much mass is packed into that volume, also density is how tight atoms are packed together
How is the metric unit of volume related to the unit of mass?
Capacity is another word for volume, which is the amount of space occupied by an object. Both mass and volume are extensive attributes of an object; that is, both depend upon the amount of stuff you have. Mass and capacity are independent of each other. A more massive (heavier) object made of a certain substance -- think gold -- may occupy far less space than a less massive (lighter) one made from a different substance -- think Styrofoam. But if you have objects made of the same substance, then a relationship between the two attributes can be established. The ratio of a substance's mass to its volume is called its mass density. The formula is simple: P = m/v, where P (the Greek letter rho) is the density. For example, if you have a ten kilograms of stuff and it occupies two cubic meters (of space), its mass density is five kilograms per cubic meter (kg/m3). So, to calculate mass density, divide an object's mass by its volume. Further, if you know an object's mass density and its volume, you can calculate its mass, and if you know an object's mass density and its mass, you can calculate its volume.
