Chapter 12: Problem 135
(a) Derive the equation relating the molality \((m)\) of a solution to its molarity ( \(M\) ) $$m=\frac{M}{d-\frac{\mathrm{M} . \mathscr{U}}{1000}}$$ where \(d\) is the density of the solution \((\mathrm{g} / \mathrm{mL})\) and \(\mathscr{M}\) is the molar mass of the solute \((\mathrm{g} / \mathrm{mol}) .\). Hint: Start by expressing the solvent in kilograms in terms of the difference between the mass of the solution and the mass of the solute.) (b) Show that, for dilute aqueous solutions, \(m\) is approximately equal to \(M\).
