mg/ml to molarity formula

The formula to convert mg/ml to molarity is:

M = milligrams per milliliter / M.Wt

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

How to convert mg/ml to molarity?

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

Here’s a step-by-step guide:

  1. Determine the molecular weight (g/mol)
  2. Concentration(mg/ml) divided by molecular weight
  3. Last, calculation you get molarity in mol/l

Solved Example

Example – A solution with a concentration of 50 mg/ml, and the molecular weight of the solute is 150 g/mol then calculate the molarity.

Solved

Given, Concentration = 50 mg/ml, Molecular weight = 150 g/mol

Molarity = (50 mg/ml) / 150 = 0.333 M

the molarity of the solution is approximately 0.333 M.
