Potassium Chromate Composition and Molar Mass • …
The molar mass of elements in grams per mole is numerically equal to their atomic mass in unified atomic mass units (u) or daltons (Da). The molar mass of compounds is equal to the sum of molar masses of the atoms which form the compound. For example, the molar mass of water (H₂O) is approximately 1 × 2 + 16 = 18 g/mol.
