Proteins can have the same number of amino acids (and therefore same mass) yet be different proteins due to the different order of amino acids.
The relative molecular mass of CaCO3 (calcium carbonate) is approximately 100.09 g/mol.
They are the calculated averages of all the isotopes of a particular element in accordance to their relative abundances, and hence is generally not an integer due to the mathematical division involved.
Molecular mass is the sum of the atomic masses of all the atoms in a molecule. It is usually expressed in atomic mass units (amu) or grams per mole (g/mol). Molecular mass is used to determine the mass of a substance in chemical reactions and stoichiometry calculations.

Water is composed of two hydrogen and an oxygen atom. Their respective atomic numbers are 1 and 16. Therefore the RMM of water is 2x1+16=18.

The symbol Mr in chemistry stands for the relative molecular mass of a compound. It represents the average mass of a molecule of the compound compared to one-twelfth of the mass of an atom of carbon-12.
Relative molecular mass is obtained by summing up the atomic masses of atoms in the formula. The gram molecular mass denotes the mass of a mole of the substance in grams. Both of them are same in number.
The Atomic Mass of Mg is 24. The atomic mass of fluorine is 19. Therefore the relative mass of the substance is 62.
The relative atomic mass of sulfur is 32.06 g/mol and the relative atomic mass of oxygen is 16.00 g/mol. Therefore, the relative molecular mass of SO2 (sulfur dioxide) is 32.06 + (16.00 x 2) = 64.06 g/mol.
The relationship between molecular mass and vapor density is that they are proportional to each other. Vapor density is defined as the mass of a vapor relative to the mass of an equal volume of air, while molecular mass is the mass of a molecule of a substance. Therefore, a higher molecular mass will result in a higher vapor density.
Water is composed of two hydrogen and an oxygen atom. Their respective atomic numbers are 1 and 16. Therefore the RMM of water is 2x1+16=18.
They are called isotopes. They differ in molecular mass due to the different number of neutrons.
