What is the formula for molarity

The formula for molarity is:

$$\text{Molarity (M)} = \frac{\text{Moles of solute}}{\text{Volume of solution in liters}}$$

Or, using common symbols:

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

where:

• $M$ is molarity (in $\text{mol/L}$ or $\text{mol/dm}^3$)
• $n$ is the number of moles of solute (in $\text{mol}$)
• $V$ is the volume of the solution (in $\text{L}$ or $\text{dm}^3$)
