Molar mass is the amount of mass contained in 1 mole of substance. Mol is a word derived from the Latin “mole”, which can mean “lot”, “portion”, “quantity”, “heap”. It is the International System unit used to determine the quantity of elementary particles.
The mole is a quantity and not a unit of measure, it is related to Avogadro's Constant, NA, which corresponds to 6.02 x 1023 atoms, ions or molecules of a substance.
|Molar Mass Units|
|Gram per mol (g/mol)|
|Kilogram per mol (kg/mol)|
|Hydrogen molecule (H2)|
|Water molecule (H2O)|
|Sodium chloride (Table salt) (NaCl)|
|Chlorine gas molecule (Cl2)|
|Sulfur molecule (S8)|
|Sugar (sucrose) (C12H22O11)|
To perform the molar mass calculation it is necessary to obtain the atomic mass of the elements that make up the molecule, these data are obtained from a periodic table.
Then just add the atomic masses of each element of the molecule, the result should be in g/Mol (grams per Mol).
