Calculate the molality of a solution prepared from dissolving 0.50 moles of ethanol in 5 moles of water
5 moles H2O = 5 x 18 = 90 g = 0.090 kg.
molality of the solution is mols solute/kg solvent = 0.50 mol solute/0.090 kg solvent = ?
molality of the solution is mols solute/kg solvent = 0.50 mol solute/0.090 kg solvent = ?
