Please let us know how we can improve this web app. Related: Molecular weights of amino acids Weights of atoms and isotopes are from NIST article. 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) This periodic table is created by Dr Kaisa Helttunen and Heikki. Please note that the chemical formula is not limited to the known chemical compounds.
So, in our example, carbon has a molar mass of 12.01 grams per mole. For example, if you want to find the molar mass of carbon, you would find the atomic mass of carbon on the periodic table, and this is equal to the molar mass in grams per mole. Options for hiding the symbol or name of the elements provide a handy learning aid for memorizing the periodic table. The molar mass of elements is found by looking at the atomic mass of the element on the periodic table. Molecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). Use this visual tool for calculating molar mass for any chemical formula.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:ĭefinitions of molecular mass, molecular weight, molar mass and molar weight The mass of one atom of carbon-12 the atomic mass of carbon-12 is exactly 12 atomic mass units. 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) Mathematically, the defining equation of molar mass is Molar mass mass/mole g/mol The definition of atomic mass, the mole, and molar mass are all directly or indirectly related to carbon-12. Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg Relevant for: Polymer melts, Polypropylene, Carreau-Yasuda Regression, Frequency Sweep, Molar Mass, Weight Average Molar Mass, Zero Shear Viscosity.
Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al. Putting in a molecular formula of any type such as K2Cr2O7, CH3CH2COOH, KFeFe(CN)63, or Na2B4O7.10H20 will result in the molar mass and mass analyses. 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.Enter a chemical formula to calculate its molar mass and elemental composition:Ĭomputing molar mass (molar weight)To calculate molar mass of a chemical compound enter its formula and click 'Compute'. 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. The lightest chemical element is Hydrogen and the heaviest is Hassium. The chemical elements ofįor chemistry students and teachers: The tabular chart on the right is arranged by Atomic mass (weight). Enter a valid molecular formula and press. This list contains the 118 elements of chemistry. Determine the Molar mass and Percent mass composition of a linear chemical formula.
