The molar mass of a compound is the sum of atomic weights of the contained elements in the molecule.
The expression atomic weight is correct for elements; for isotopes is correct atomic mass.

How are atomic mass and atomic number related?
The Atomic Mass number is the sum of the atomic number, the number of protons, and the number of neutrons in the nucleus of the atom.
How was atomic mass first calculated?
The atomic mass is determined by accurate mass spectrometry. If you think to atomic weight, 200 years ago, this parameter was related to hydrogen with a given atomic weight of 1.
How are the atomic mass unit and the atomic mass related?
because they are the sameAdded:Atomic mass is the quantitive propertie of the mass of an atom,the atomic mass unit is the (standard) UNIT by which it is measured:1 a.m.u. = 1.66*10-27 kg
Atomic mass of copper?
Copper can be found on the Periodic Table of Elements. Copper's symbol is Cu, and the atomic number is 29. The atomic mass is hard to find searching the Internet, but here it is. The atomic mass for Copper is 63.546, also recognized as just 63.Atomic Number: 29Atomic mass: 63.546, or just 63**Note: The atomic mass for Copper and some other chemicals cannot be found on WebElements.
How is the atomic mass for chlorine related to isotopes for that atom?
The average atomic mass is weighted by the most common isotopes and their relative abundance.
What element has a atomic mass of 114.82?
Indium (In) has an atomic mass of 114.818g/mol
What is relative atomic mass and how it is related with gram?
when atomic mass of an element expressed in gram atom is called gram atom mass . and formula is number of gram atom=given mass (in gram) by atomic mass ( in gram )
How are atomic mass and atom numbers related?
The mass number is the number of the Atomic Mass. The atomic mass is the mass of the atom of the element. There is no difference between the two, except mass number is referring to the number, while atomic mass is referring to the atom's mass in general, which is also expressed by a number. Basically, both terms mean the exact same thing.
What is atomic mass and the number of calcium?
Calcium has atomic number of 20, an atomic weight of 40.078 and an mass numbers of 40 - 48 inclusive in its isotopes. Atomic number is the count of protons in the nucleus. Mass number is the count of protons plus neutrons. The question refers to atomic mass rather than atomic weight. Atomic mass normally refers to the mass of a specific isotope of an element and is related to the mass number. Atomic weight ( or relative atomic mass as it is termed by IUPAC) the average mass of naturally occurring isotopes of an element. The relationship between mass number and atomic mass is defined in terms of the Atomic mass unit which is in simple terms 1/12 of the mass of a 12C atom. If you need to find out more about the relationship between mass number and and atomic mass you need to read the article "atomic mass unit" in wikipedia.
