Calculate the milligrams of chlorine (35.453 g/mol) in a 4.28 g solution of 22.2 wt% CaCl2 (110.98 g/mol).

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:

Step 3

The mass percentage as 22% of CaCl2 depicted as 22 g of CaCl2 is dissolved in 100 g of...
