The term "average atomic mass" is a average, and so is calculated differently from a "normal" average. 2. The element copper has naturally occurring isotopes with mass numbers of 63 and 65. The relative abundance are 69.2% and 30.8% respectively. 6.2 Solids, liquids and gases | Particle model of matter ... The mass of an object or a substance tells us how much matter it consists of. The greater the mass of an object, the more matter it contains. Mass is measured in kilograms (kg). When we measure the mass of small objects or small amounts of matter we often measure in grams (g) or even milligrams (mg). One kilogram is the same as 1000 grams.
