ohh ok!
Molar mass is a mass in grams (more detail below), and it can can refer to an element or to a chemical compound made of more than one element. There are way too many chemical compounds to make a list of them, and living creatures (including chemists) are making new ones every day.
Atomic mass is a number that refers to the relative mass of one atom, relative to the mass of 1/12 of an atom of carbon 12. It is just a ratio, a number. When we want to name the units, we say atomic mass units (abbreviated amu). We classify atoms by their properties into kinds we call elements, like carbon, oxygen, gold, etc. There are many elements, but not so many that we could not list them all. Most of the time chemists do not care about individual atoms, because there are
billions of billions of billions of atoms in the smallest drop of water.We deal with groups of atoms and care about the average atom. Each element may have atoms with different weights, but they have common properties, and we call those varieties isotopes. The mixture of isotopes of each element found in nature has an average atomic mass that we call atomic weight. When we list atomic weights, we often list the units as Daltons.
