How many moles are contained in 1.19 g of h2o
Web30 nov. 2024 · Assume we want to dissolve 70.128 grams of salt in 1.5 kg of water. So: moles of NaCl = 70.128 g / (58.44 g/mol) = 1.2 mol. Plug the number of moles and the mass of the solvent into the molality formula. Divide 1.2 mol by 1.5 kg, and you'll find out that the molality of the NaCl solution is 0.8 molal (in standard molality units: 0.8 mol/kg).
