This is the molar mass.
The sum of the atomic masses in a molecule is called the molecular weight or molecular mass. It is calculated by adding the atomic masses of all the atoms in the molecule. This value is usually expressed in atomic mass units (amu) or grams per mole (g/mol).
it is the sum of the atomic masses of all the elements present in a molecule.
The formula mass of a molecule or an ion is the sum of the atomic masses of all the atoms in the formula unit. This value is expressed in atomic mass units (amu) and is used to calculate the molar mass of the compound.
molecular mass
The atomic mass of an element is listed on the periodic table, generally below the name of the element. The molar mass of a molecule will be generally be the sum of the atomic masses of the elements that make up the molecule.
The antonym of atomic number would be molecular mass. Atomic number refers to the number of protons in an atom's nucleus, while molecular mass refers to the mass of a molecule, which is the sum of the atomic masses of its atoms.
The grand formula mass is the sum of the masses of all the atoms in a single molecule of a compound, including all elements present in that compound. It is calculated by adding up the atomic masses of each element involved in the molecule.
sum the masses of its constitutes
The size of C12H26 (dodecane) molecule can be approximated by calculating the sum of the atomic masses of its constituent atoms. C12H26 has a molecular weight of approximately 170 g/mol.
Protons and neutrons.
The molar mass of a molecule is the sum of atomic weights of the elements contained in this molecule.
