+ | $M_1V_1 = M_2V_{total}$ | ||
+ | |||
+ | Note that $M*V = \text{moles}$. $M$ represents molarity and $V$ volume. | ||

+ | ==== Example ==== | ||
+ | What if a 1M 10mL solution was diluted with 10mL extra water? | ||
+ | * $1M \times 10\text{mL} = ?M \times 20\text{mL}$ | ||
+ | * $M = 0.5M$ The result is a halved molarity! |
