At 25oC, 5.77 grams of chlorine gas dissolves in enough water to give 1.0 L of solution. What is the molarity of the solution? (Atomic weight: Cl = 35.45).

Explanation:

Molarity is defined as the number of moles present in a liter of volume.

Mathematically,     Molarity = [tex]\frac{\text{number of moles}}{volume}[/tex]

Also, we know that number of moles equal mass divided by molar mass.

Hence, we will calculate the number of moles of chlorine as follows.

                 No. of moles = [tex]\frac{mass}{\text{molar mass}}[/tex]

                                       = [tex]\frac{5.77 g}{35.45 g/mol}[/tex]

                                       = 0.162 mol

Therefore, molarity of the given solution will be calculated as follows.

               Molarity = [tex]\frac{\text{number of moles}}{volume}[/tex]

                              = [tex]\frac{0.162 mol}{1 L}[/tex]

                              = 0.162 M

Thus, we can conclude that the molarity of given solution is 0.162 M.
