## Question:

In neutralization reactions, acid + base {eq}\rightarrow {/eq} salt + water, HCl can be neutralized with NaOH. How many moles of NaOH will it take to neutralize 0.68 L of 0.29 M HCl?

## Molarity

The molarity M of a solution is the ratio between the amount of solute n in moles and the volume of the solution V in liters. In mathematical terms,

$$M = \frac{n}{V}$$

$$HCl \ (aq) + NaOH \ (aq) \to NaCl \ (aq) + H_2O \ (l)$$
