Expert Answer

Step 1

The concentration of any substance can be expressed in different ways such as molality, molarity, normality etc. Some other ways are ppm, ppb, mole fraction and mass percentage.

Step 2

Mass percent or weight percent of a solution is the mass of the solute by the mass of the solution multiply by 100. The mathematical expression for molality can be written as:
