WebStep 1 - Calculate the relative formula mass of the empirical formula. (C x 4) + (H x 10) + (S x 1) = (12 x 4) + (1 x 10) + (32 x 1) = 90. Step 2 - Divide the relative formula mass of X by the mass of the empirical formula. 180 / 90 = 2. Step 3 - Multiply each number of elements by 2. WebOne mole of sodium chloride (NaCl) contains 6.02 x 10 23 formula units of sodium chloride; The mass of 1 mole of a substance is known as the molar mass; For an element, it is the same as the relative atomic mass written in grams; For a compound it is the same as the relative formula mass or relative molecular mass in grams
