Related: Molecular weights of amino acids The molar mass of hydrogen gas is 2.016 grams per mole. Weights of atoms and isotopes are from NIST article. molar mass of the gas, and (iii) molecular formula.

Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol. Hydrogen peroxide is a chemical compound with the formula H 2 O 2.In its pure form, it is a very pale blue liquid that is slightly more viscous than water.It is used as an oxidizer, bleaching agent, and antiseptic, usually as a dilute solution (36 by weight) in water for consumer use, and in higher concentrations for industrial use.

(1 u is equal to 1/12 the mass of one atom of carbon-12) Molecular formulas give the kind and number of atoms of each element present in the molecular compound.

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:ĭefinitions of molecular mass, molecular weight, molar mass and molar weight

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) Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg.

If all the hydrogen is fully inonized, then the mass of one hydrogen atom (1 amu) would. The mass calculator on the right may be used to calculate the. Determine the molecular formula of the compound. The empirical formula of a compound of boron and hydrogen is BH3 BH 3. 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. Then the mean mass per particle in amus would be 1, making 1. Multiply all the subscripts in the empirical formula by the whole number found in step 2.

Hydrogen is a colorless, odorless, and highly flammable gas.Ĭomputing molar mass (molar weight)To calculate molar mass of a chemical compound enter its formula and click 'Compute'.
