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.
relative atomic mass
relative Atomic Mass
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.
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
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.
The average atomic mass is weighted by the most common isotopes and their relative abundance.
by Atomic Mass
No, atomic mass and atomic number are not directly proportional to each other. Atomic mass represents the average mass of isotopes of an element, while atomic number represents the number of protons in an atom's nucleus. These values are related but not directly proportional.
Indium (In) has an atomic mass of 114.818g/mol
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 )
The atomic mass is a property that refers to the average mass of an atom of an element. It is measured in atomic mass units (amu) or grams per mole. The atomic mass is not directly related to pounds, which is a unit of weight in the imperial system.
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.
