$M_AV_A$ = $M_BV_B$

Let's assume you are titrating a strong acid (10 mL unknown concentration HCl) with a strong base (1.0 M NaOH). It takes 25mL of NaOH to neutralize the acid. If you solve for $M_A$ you will see that

$M_A$ = ( $M_BV_B$ ) / $V_A$

or $M_A$ = (1.0M x 25mL) / 10

$M_A$ = 2.5M HCl

This works because M = moles/L

*Note: You do not need to convert volumes of acid and base to liters as long as both are expressed in same unit (mL).
