We are going to calculate the mass percent, mole fraction, molarity, and morality of KCl in a solution prepared by dissolving 24.0 g of KCl in 225 g of water.

**A. Mass percent**

$\overline{){\mathbf{Mass}}{\mathbf{}}{\mathbf{percent}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}\frac{\mathbf{g}\mathbf{}\mathbf{solute}}{\mathbf{g}\mathbf{}\mathbf{solution}}{\mathbf{\times}}{\mathbf{100}}}$

A solution was prepared by dissolving 24.0 g of KCl in 225 g of water.

A. Calculate the mass percent of KCl in the solution

B. Calculate the mole fraction of the ionic species KCl in the solution.

C. Calculate the molarity of KCl in the solution if the total volume of the solution is 239 mL.

D. Calculate the molality of KCl in the solution.
