How many sig figs for molarity

Web2 apr. 2024 · You can see that in NaCl, there is 1 Sodium atom and 1 Chlorine atom. So, Molar mass of NaCl = Molar mass of 1 Sodium (Na) atom + Molar mass of 1 Chlorine (Cl) atom. = 22.99 + 35.45. = 58.44 g/mol. Hence the Molar mass of NaCl is 58.44 g/mol. I hope you have understood the short and simple calculation for finding the molar mass of NaCl. WebSince the molar mass (gram formula mass of sodium chloride is 58 grams per mole ( Na = 23 g and Cl = 35 g , 23 + 35 = 58 g/mol) the mole value of the NaCl is 0.5 moles (29 g / 58 g/mol = 0.5 moles). The mass of water is 1000 grams which is converted to 1.0 kg. Molality = moles of solute / kg of solvent. Molality = 0.5 moles / 1.0 kg = 0.5 molal.
