## Molarity to mg/ml formula

The formula to convert molarity to mg/ml is:

**mg/ml = M * M.Wt**

- M = Molarity
- mg/ml = milligrams per milliliter
- M.Wt = Molecular Weight (molar mass) in g/mol

## How to convert molarity to mg/ml?

To convert molarity (M) to milligrams per milliliter (mg/ml), you’ll need to know the molecular weight of the substance.

Here’s a step-by-step guide:

- Determine the molecular weight (g/mol)
- Molarity multiplied by molecular weight
- Last, calculation you get concentration in mg/ml

## Solved Example

**Example **– A solution with a molarity of 0.002 M, and the molecular weight of the solute is 100 g/mol then calculate concentration in mg/ml.

Solved –

Given value, Molarity = 0.002 M , Molecular Weight = 100 g/mol

Concentration (mg/ml) = 0.002 M * 100 g/mol

Concentration (mg/ml) = 0.2 mg/ml

The concentration of the solution in milligrams per milliliter is 0.2 mg/ml.
