How to calculate ions from grams
WebRemember, the idea is to choose the one that allows canceling the gram units. So, it should be the one where the grams are in the denominator. n(S) = 5.20g × 1mol S 32.1gS = 0.162mol Once we have the number of moles, we use another conversion factor linking it with the Avogadro’s number. 1molS 6.03 × 1023atomsofS or 6.03 × 1023atomsofS 1 mol S WebAs an illustration, suppose you have mixed 25 g of NaCl (common salt) into 2 litres of water then first you have to determine the numbers of moles in 25 g of NaCl (Salt). Besides, one mole of Sodium Chloride (NaCl) has a mass of approximately 58.5 grams. And it gives the conversion factor of 1 / 58.5.
