### Example Question #471 : High School Chemistry

30mL of a solution of of unknown concentration mixed with 19mL of produced a solution with a pH of 7. What is the concentration of the solution?

**Possible Answers:**

None of these

**Correct answer:**

For this question use the following formula:

is the number of acidic hydrogens on the acid, _{ }is the molarity of the acid, _{ }is the volume of the acid, _{ }is the number of basic hydroxides on the base, _{ }is the molarity of the base, _{ }is the volume of the base

Rearrange the equation for the molarity of the base:

Plug in known values and solve.
