If you have 25.0 ml of a 6.50m naoh solution and you add 10.0 ml of water to it, what is the new concentration?

Explanation:

The given data is as follows.

        = 25.0 ml,       = (10.0 ml + 25.0 ml) = 35.0 ml

        = 6.50 M,        

Relation between volume and molarity of the two liquids is as follows.

        =

        =    

              = 4.64 M

Thus, we can conclude that new concentration is 4.64 M.

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.
