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 =

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 =

                                       =

                                       = 0.162 mol

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

               Molarity =

                              =

                              = 0.162 M

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

the answer is definitely c.
