How to Calculate Moles.
Formula to calculate moles. Mass of one mole of the substance can be found in a periodic table. Example: Determine the moles in 20.0 grams of NaCl. Since we know from the periodic table that the mass of one mole of sodium chloride is 58.44 grams, then; Therefore, the number of moles in 20.0 grams of sodium chloride is 0.34.
