Understanding Molecular Weight, Molar Mass, and Formula Weight

Molecular Weight

Molecular weight refers to the sum of atomic weights of all atoms in a molecule. It is expressed in atomic mass units (amu) or grams per mole (g/mol).

Example:
Water (H₂O) = 2(1.008) + 16.00 = 18.016 g/mol

Molar Mass

Molar mass is the mass of one mole of a substance, typically in grams per mole. It’s crucial for stoichiometry and solution preparation.

Example:
Glucose (C₆H₁₂O₆) = 6(12.01) + 12(1.008) + 6(16.00) = 180.16 g/mol

Formula Weight

Formula weight is the sum of atomic weights in the empirical formula of a compound. It is especially useful for ionic compounds where molecules are not distinct.

Example:
Sodium chloride (NaCl) = 22.99 + 35.45 = 58.44 g/mol
