The massof an object is how much matter there is in the object.
You weight it.
The amount of mass in a certain volume of matter is called density. Density is calculated by dividing the mass of an object by its volume, and it represents how much mass is contained in a specific amount of space.
mass = volume X density
Mass.
The amount of matter (mass) in a certain amount of space (Volume).
It has like more dense
Mass per unit volume is the object's "Density".
Density is the amount of mass in a certain unit volume of a substance (Density equals mass divided by volume).
The amount of mass an object has in a certain volume is known as its density. Density is calculated by dividing the mass of the object by its volume. It is typically measured in units such as grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
mass is the amount of matter (stuff) you're made out of, so it won't change unless you add or subtract something.
Properties which a certain amount of gas will maintain include its mass, and the number of moles.
place an object in a container with a fluid and find the amount of water it displaced. then find the mass of the object. then multiply the mass by the amount of displaced water♪
