Wanna quickly interchange between Percentage Concentration to Molarity and needed a handy tool? Then this Percentage Concentration to Molarity Calculator can be of extreme help as it makes your calculations much simple. Simply enter the inputs like name of the solution, molar mass, density, percent and tap on the calculate button to get the molarity value in the blink of an eye.

Your Molar Mass

What does Molarity mean?

Molarity of a Solution is defined as the total number of moles of solute per liter of solution. Molarity is denoted by the letter or symbol 'M'. Usually, Concentrations are expressed in terms of molarity.

Percentage Concentration - Definition

Percentage Concentration is the measure for determining the amount of solute dissolved in every 100 units of solution. It is denoted by the symbol %.

Percentage Concentration to Molarity Formula

In order to determine the Molarity from Percentage Concentration use the following formula: Molarity = (Percentage concentration * Density ) / (Molar mass * 100). However, units related to the formula are as such

  • Molarity -> mol/dm³ = M = mol/L
  • Percentage concentration -> %
  • Density -> g/L = g/dm³ or g/mL or g/cm³ or kg/m³

If you want to find out Percentage Concentration then simply rearrange the above formula i.e. Percentage concentration = (Molarity * Molar mass * 100)/ Density
