Enter the molarity and molar mass of a solution into the calculator to convert the concentration from molarity (M) to grams per liter (g/L).

Molarity to Grams/Liter Formula

The following formula is used to convert molarity to grams per liter.

g/L = M * MM

Variables:

  • g/L is the concentration in grams per liter
  • M is the molarity of the solution (moles per liter)
  • MM is the molar mass of the solute (grams per mole)

To convert molarity to grams per liter, multiply the molarity (M) by the molar mass (MM) of the solute.

What is Molarity?

Molarity 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 commonly used in chemistry to express the concentration of chemical substances. To calculate molarity, one must know the amount of solute (in moles) and the volume of the solution (in liters).

How to Calculate Grams per Liter from Molarity?

The following steps outline how to calculate the concentration in grams per liter from molarity.

  1. First, determine the molarity (M) of the solution in moles per liter.
  2. Next, determine the molar mass (MM) of the solute in grams per mole.
  3. Use the formula g/L = M * MM to calculate the concentration in grams per liter.
  4. Finally, enter the values into the calculator above to verify the result.

Example Problem :

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

Molarity (M) = 2 M

Molar Mass (MM) = 58.44 g/mol (for NaCl)
