S Sulfur 32.065 1 12.2629 %

O Oxygen 15.9994 4 24.4752 %

H Hydrogen 1.00794 140 53.9667 %

Explanation:

Computing molar mass (molar weight)

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

Any chemical element

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

parantesis () or brackets [].

Common compound names.

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

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 of molecular mass, molecular weight, molar mass and molar weight

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.

Weights of atoms and isotopes are from NIST article.

The formula of Epsom salt is MgSO4.7H2O

The molecular weight of it is 246 amu.

% of Mg = (24/246)x100 = 9.75%

% of S = (32/246)x100 = 13%

% of O = (176/246)x100 = 71.54%

% of H = (14/246)x100 = 5.7%

Hope it helps!!


bhawnabhardwaj2: thank a lot
