The concentration of a solution can be calculated using the equation:
concentration of solution=mass of dissolved solidvolume of solution \text{concentration of solution} = \frac{\text{mass of dissolved solid}}{\text{volume of solution}} concentration of solution=volume of solutionmass of dissolved solidA student dissolved 8.75 g of potassium chloride in water and made the solution up to a total volume of 250 cm3^33.
Use the equation to calculate the concentration of this solution in g dm−3^{-3}−3.
