How many grams of kcn are in 10.0 ml of a 0.10 m solution?

Explanation:

As it is known that molarity is the number of moles present in a liter of solution.

Mathematically,       Molarity =

As it is given that molarity is 0.10 M and volume is 10.0 ml. As 1 ml equals 0.001 L. Therefore, 10.0 ml will also be equal to 0.01 L.

Hence, putting these values into the above formula as follows.

                  Molarity =

                  0.10 M =

                        no. of moles = 0.001 mol

As molar mass of KCN is equal to 65.12 g/mol. Therefore, calculate the mass of KCN as follows.

                 No. of moles =

                                 0.001 mol =

                                 mass = 0.06152 g

Thus, we can conclude that 0.06152 grams of KCN are in 10.0 ml of a 0.10 M solution.
