WebOne formula unit of sodium chloride (NaCl) would weigh 58.44 amu (22.98977 amu for Na + 35.453 amu for Cl), so a mole of sodium chloride would weigh 58.44 grams. One molecule of water (H 2 O) would weigh 18.02 amu (2×1.00797 amu for H + 15.9994 amu for O), and a mole of water molecules would weigh 18.02 grams. WebSep 3, 2024 · In many cases, the molecular formula is the same as the empirical formula. The chemical formula will always be some integer multiple ( n) of the empirical formula (i.e. integer multiples of the subscripts of the empirical formula). Molecular Formula = n ( Empirical formula) therefore n = Molecular Formula Empirical Formula
