If 35 mL of a .5 m hydrochloric acid solution is required to neutralize 15 mL of a sodium hydroxide solution of unknown concentration, what is the molarity of the sodium hydroxide solution

The molarity of the sodium hydroxide solution is 1.16 M.

Explanation:

Given: = 35 mL,     = 0.5 M

= 15 mL,           = ?

Formula used to calculate the molarity of the sodium hydroxide solution is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that the molarity of the sodium hydroxide solution is 1.16 M.
