For atoms, after IUPAC rule, the term used is atomic weight. The unit is "unified Atomic Mass unit", not included in SI.
For molecules the term is molecular (molar) mass. The unit is kg/mol.
What else can I help you with?
What has mass volume and is made of atoms?
molecules
What is the unit of weight for elements?
The unit of weight for elements is typically measured in atomic mass units (amu) or grams. The atomic mass unit is defined as one twelfth of the mass of a carbon-12 atom.
Which two elements make up the most common compound in the human?
Hydrogen and oxygen Water is the most common molecule, between 55 and 65% of our mass. Hydrogen accounts for 63% of our atoms, but oxygen accounts for 65% of our mass. (Both hydrogen and oxygen are part of many other molecules besides water.)
Which elements make up the most common compound in the human body?

What creates a compound?
a compound is any arrangement of two or more atoms of different elements; usually refers to a mass of molecules, or singular units of a compound
What weighs more hydrogen atoms or carbon atoms?
Carbon atoms would weigh more because they have six protons and six neutrons. The most common form of Hydrogen has one proton and no neutrons, which means that Carbon is normally about 12 times as heavy as Hydrogen (in their most common forms).
What tells you how heavy an element's atoms are compared with atoms of other elements?
The atomic mass of an element tells you how heavy its atoms are compared with atoms of other elements. Atomic mass is the average mass of an atom of an element, taking into account all its isotopes and their abundance.
How do you find the molar mass of an elemnt?
Molar mass is a term applied for molecules, not for atoms.
Does air have mass because it is composed of atoms and molecules?
yes.
Why do Atoms and molecules have kinetic Energy?
Because they: * Have mass * Have a speed

What do you mean by molar mass of an element?
Molar mass is defined as the mass of 6.022x1023 atoms/molecules of a given substance.
