Vedclass · Answer

(D) Molality is defined as the number of moles of solute per kilogram of solvent $(m = n_{solute} / W_{solvent(kg)})$. In the given problem,we are provided with the total mass of the solution $(100 \ g)$ and its molality $(0.2 \ m)$. Since the molar mass of the solute is unknown,we cannot determine the mass of the solvent in the initial $100 \ g$ solution. Because the final molality depends on the initial mass of the solvent,which cannot be calculated without knowing the identity of the solute,the final molality cannot be determined.

If $100 \ g$ of a $0.2 \ m$ aqueous solution is diluted by adding $200 \ g$ of water,what will be the molality of the resulting solution?
