What is the molarity of a nacl stock used to make 750 ml of a dilute 10 mm solution if 5 ml of the concentrated solution was used?

Explanation:

The given data is as follows.

          = 10 mM = M

          = 750 ml,           = 5 ml

          = ?

Therefore, calculate the molarity of given NaCl stock as follows.

                    = 1.5 M

Thus, we can conclude that molarity of given NaCl stock is 1.5 M.        

have a great day because if you dont you and i will be sad
