Computing molar mass step by step
First, compute the number of each atom in H₁₀₀₀₀Li₁₀₀Be₁₀₀Na₁₀₀Mg₁₀₀K₁₀₀Ca₁₀₀Rb₁₀₀Sr₁₀₀Cs₁₀₀Ba₁₀₀Fr₁₀₀: H: 10000, Li: 100, Be: 100, Na: 100, Mg: 100, K: 100, Ca: 100, Rb: 100, Sr: 100, Cs: 100, Ba: 100, Fr: 100 Then, lookup atomic weights for each element in periodic table: H: 1.00794, Li: 6.941, Be: 9.012182, Na: 22.98976928, Mg: 24.305, K: 39.0983, Ca: 40.078, Rb: 85.4678, Sr: 87.62, Cs: 132.9054519, Ba: 137.327, Fr: 223.0197359 Now, compute the sum of products of number of atoms to the atomic weight: Molar mass (H₁₀₀₀₀Li₁₀₀Be₁₀₀Na₁₀₀Mg₁₀₀K₁₀₀Ca₁₀₀Rb₁₀₀Sr₁₀₀Cs₁₀₀Ba₁₀₀Fr₁₀₀) = ∑ Count_i * Weight_i = Count(H) * Weight(H) + Count(Li) * Weight(Li) + Count(Be) * Weight(Be) + Count(Na) * Weight(Na) + Count(Mg) * Weight(Mg) + Count(K) * Weight(K) + Count(Ca) * Weight(Ca) + Count(Rb) * Weight(Rb) + Count(Sr) * Weight(Sr) + Count(Cs) * Weight(Cs) + Count(Ba) * Weight(Ba) + Count(Fr) * Weight(Fr) = 10000 * 1.00794 + 100 * 6.941 + 100 * 9.012182 + 100 * 22.98976928 + 100 * 24.305 + 100 * 39.0983 + 100 * 40.078 + 100 * 85.4678 + 100 * 87.62 + 100 * 132.9054519 + 100 * 137.327 + 100 * 223.0197359 = 90955.8239 g/mol

Computing molar mass (molar weight)

To calculate molar mass of a chemical compound enter its formula and click 'Compute'. In chemical formula you may use:

Any chemical element. 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.
Functional groups: D, T, Ph, Me, Et, Bu, AcAc, For, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg
parenthesis () or brackets [].
Common compound names.

Examples of molar mass computations: NaCl, Ca(OH)2, K4[Fe(CN)6], CuSO4*5H2O, nitric acid, potassium permanganate, ethanol, fructose, caffeine, water.

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.

Computing molecular weight (molecular mass)

To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.
Examples of molecular weight computations: C[14]O[16]2, S[34]O[16]2.

Definitions

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
Mole is a standard scientific unit for measuring large quantities of very small entities such as atoms and molecules. One mole contains exactly 6.022 ×10²³ particles (Avogadro's number)

Steps to calculate molar mass

Identify the compound: write down the chemical formula of the compound. For example, water is H₂O, meaning it contains two hydrogen atoms and one oxygen atom.
Find atomic masses: look up the atomic masses of each element present in the compound. The atomic mass is usually found on the periodic table and is given in atomic mass units (amu).
Calculate molar mass of each element: multiply the atomic mass of each element by the number of atoms of that element in the compound.
Add them together: add the results from step 3 to get the total molar mass of the compound.

Example: calculating molar mass

Let's calculate the molar mass of carbon dioxide (CO₂):

Carbon (C) has an atomic mass of about 12.01 amu.
Oxygen (O) has an atomic mass of about 16.00 amu.
CO₂ has one carbon atom and two oxygen atoms.
The molar mass of carbon dioxide is 12.01 + (2 × 16.00) = 44.01 g/mol.

Weights of atoms and isotopes are from NIST article.
