Determine the molar mass of lithium bromide
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. WebJan 2, 2016 · 1 Answer. anor277.
