WebHow many moles are in 50g of NaCl? We do this by looking up the relative atomic masses of Na and Cl in the periodic table. Na has an atomic mass of 23 and Cl is 35.5. So the Mr(NaCl)= 23 + 35.5 = 58.5. Putting all of this into our moles equation gives us the answer: moles= 50/58.5 = 0.855 moles (3sf). http://scientifictutor.org/1021/chem-how-to-convert-between-grams-and-molecules/
