Question

A solution was prepared by dissolving 26.0 g of KCl in 225 g of water.

The composition of a solution can be expressed in several different ways. Four of the most common concentration units are defined as follows:. mass %=mass of componenttotal mass of solution×100%; mole fraction (X)=moles of componenttotal moles of solution; molarity (M)=moles of soluteliters of solution; molality (m)=moles of solutemass of solvent (kg)

Part A

Calculate the mass percent of KCl in the solution.

Part B

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

Part C

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

Part D

Calculate the molality of KCl in the solution.
