For mole fraction we need both the # moles of solute and #moles of solvent. ... The molality of the solution is (2.4 mol C3H5(OH)3, 0.425 kg H2O)= 5.7 m ... increase the amount of dissolved NaCl in solution one must (c) raise the temperature of .... The definition of molarity is #mol/L. Substituting intothe definition we obtain:.
