## Molarity to Moles Formula

To calculate moles from molarity, you can use the formula

**n = M * V**

where,

- n = Number of moles (mol)
- M = Molarity (M or mol/L)
- V = Volume of solution (L)

## How to convert molarity to moles?

To convert molarity to moles, Simply molarity (M) multiplied by the volume(L) of the solution then you get mole value

Here step by step

- First, Determine the molarity (mol/L)
- Next, Determine the volume of the soln (L)
- Finally, Put values in the above formula

## Solved Example

**Example 1** – A solution with a molarity of 0.8 M, and the volume of the solution is 1.5 liters. Calculate the moles of solute in the solution.

**Given Values**

- Molarity (M) = 0.8 M
- Volume (V) = 1.5 L

Put values into the formula

Moles = Molarity (M) * Volume (L) = 0.8 * 1.5 = 1.2 M

so, 1.2 moles of solute in the solution

**Example 2** – If the molarity is 3 M and the volume is 25 ml, then calculate the moles

**Given Value**

- Molarity = 3M
- Volume = 25 ml =25 /1000 L = 0.025 liter

Moles = M * V = 3 M * 0.025 L = 0.075 mol
