How many moles naoh are contained in 65.0 ml of a 2.20 m solution of naoh in h2o?

Explanation:

Molarity is defined as number of moles divided by volume in liter.

Mathematically,       Molarity =

Since, it is known that 1 L equals 1000 ml so 65.0 mL equals 0.065 L.

Therefore, it is given that volume is 0.065 L and molarity is 2.20 M. Hence, calculate number of moles as follows.

            Molarity =

    Number of moles =

                                  =

                                  = 0.143 mol

Thus, we can conclude that there are 0.143 moles NaOH are contained in 65.0 mL of a 2.20 M solution of NaOH in .
