Question 12.4: The density of a 2.45 M aqueous solution of methanol (CH3OH)...

The density of a 2.45 M aqueous solution of methanol ( $CH_{3}OH$ ) is 0.976 g/mL. What is the molality of the solution? The molar mass of methanol is 32.04 g. Strategy To calculate the molality, we need to know the number of moles of methanol and the mass of solvent in kilograms. We assume 1 L of solution, so the number of moles of methanol is 2.45 mol.
