There you can find the metals, semi-conductor(s), non-metal(s), inert noble gas(ses), Halogens, Lanthanoides, Actinoids (rare earth elements) and transition metals. Please note that the elements do not show their natural relation towards each other as in the Periodic system. The unity for atomic mass is gram per mol. For instance, the relative atomic mass of zirconium (Zr) is 91.22. This is usually located under the symbol and name of the element. To find an element’s molar mass, start by checking the periodic table for the relative atomic mass of the element. The lightest chemical element is Hydrogen and the heaviest is Hassium. Molar mass is the mass in grams of 1 mole of any given substance. The chemical elements ofįor chemistry students and teachers: The tabular chart on the right is arranged by Atomic mass (weight).

Oxygen (O) has an atomic mass of about 16.00 amu.Carbon (C) has an atomic mass of about 12.01 amu.Let's calculate the molar mass of carbon dioxide (CO 2): Add them together: add the results from step 3 to get the total molar mass of the compound.Calculate molar mass of each element: multiply the atomic mass of each element by the number of atoms of that element in the compound.The atomic mass is usually found on the periodic table and is given in atomic mass units (amu). Find atomic masses: look up the atomic masses of each element present in the compound.For example, water is H 2O, meaning it contains two hydrogen atoms and one oxygen atom. Identify the compound: write down the chemical formula of the compound. There are three elements - carbon, hydrogen and oxygen - so find their atomic masses in the periodic table: 12.0107 grams per mol for carbon, 1.00794 grams per mol for hydrogen, and 15.9994 grams.One mole contains exactly 6.022 ×10 23 particles (Avogadro's number) Mole is a standard scientific unit for measuring large quantities of very small entities such as atoms and molecules.Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol.(1 u is equal to 1/12 the mass of one atom of carbon-12) Molecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u).To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.Įxamples of molecular weight computations: Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.Ĭomputing molecular weight (molecular mass) Atomic Mass: 9.0122: Beryllium: Be: 4 - Electronegativity: 10.811: Boron: B: 5 - Density: 12.0107: Carbon: C: 6 - Melting point: 14.0067: Nitrogen: N: 7 - Boiling point: 15.
