WebFeb 14, 2024 · Use this formula mass: M (N) = Mr (Cl) · 1 mol = 35,453 g/mol. It is known that the chlorine molecule is diatomic - Cl2, then the relative atomic mass of the chlorine molecule will be equal to: Ar (Cl2) = 35,453 · 2 = 70,906 amu. The relative molecular mass of the chlorine molecule will be 70,906, and the molar mass: WebMolar mass = mass/mole = g/mol. The definition of atomic mass, the mole, and molar mass are all directly or indirectly related to carbon-12. This leads to two important facts. The mass of one atom of carbon-12 the atomic mass of carbon-12 is exactly 12 atomic mass units. The mass of one mole of carbon-12 atoms is exactly 12 grams; its molar ...

WebAug 10, 2024 · The molar mass of any substance is its atomic mass, molecular mass, or formula mass in grams per mole. The periodic table lists the atomic mass of carbon as 12.011 amu; the average molar mass of carbon—the mass of 6.022 × 10 23 carbon atoms—is therefore 12.011 g/mol: WebThe lightest chemical element is Hydrogen and the heaviest is Hassium. The unity for atomic mass is gram per mol. Please note that the elements do not show their natural relation towards each other as in the Periodic system.
