Enter the concentration in mg/ml and the molecular weight in g/mol into the calculator to convert to molarity (M).

Mg/Ml To Molarity Formula

The following formula is used to convert a concentration from mg/ml to molarity (M):

M = (C / MW) * 1000

Variables:

  • M is the molarity (M)
  • C is the concentration in mg/ml
  • MW is the molecular weight in g/mol

To convert mg/ml to molarity, divide the concentration by the molecular weight and then multiply by 1000 to convert from grams to milligrams.

What is Molarity?

Molarity, denoted as M, is a measure of the concentration of a solute in a solution. It is defined as the number of moles of solute per liter of solution. Molarity is one of the most common units used to measure the concentration of a solution in chemistry.

How to Calculate Molarity from Mg/Ml?

The following steps outline how to convert the concentration from mg/ml to molarity (M).


  1. First, determine the concentration (C) in mg/ml.
  2. Next, determine the molecular weight (MW) in g/mol.
  3. Use the formula M = (C / MW) * 1000 to calculate the molarity.
  4. Finally, enter the values into the calculator to get the molarity (M).

Example Problem :

Use the following variables as an example problem to test your knowledge.

Concentration (C) = 50 mg/ml

Molecular Weight (MW) = 150 g/mol
