G/Mol to G/L Formula

The following formula is used to calculate grams per liter (g/L) from molar mass (g/mol) and molarity (mol/L).

g/L = (g/mol) \times (mol/L)

Variables:

  • g/mol is the molar mass of the substance in grams per mole.
  • mol/L is the molarity (amount-of-substance concentration) in moles per liter.
  • g/L is the mass concentration in grams per liter.

To calculate g/L from g/mol, you must also know the molarity (mol/L). Multiply the molar mass by the molarity.

What is G/Mol to G/L Conversion?

Grams per mole (g/mol) is a molar mass, while grams per liter (g/L) is a mass concentration. There is no direct unit conversion from g/mol to g/L unless you also know the concentration in moles per liter (mol/L), commonly called molarity.

How to Calculate G/Mol to G/L?

The following steps outline how to calculate grams per liter (g/L) from molar mass (g/mol).


  1. First, determine the molar mass of the substance (g/mol).
  2. Next, determine the molarity of the solution (mol/L).
  3. Use the formula g/L = (g/mol) × (mol/L).
  4. Finally, calculate the concentration in grams per liter (g/L).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

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

Molar Mass (g/mol) = 58.44 g/mol (Sodium Chloride)

Molarity (mol/L) = 1.00 mol/L (1.00 M)

Result (g/L) = (58.44 g/mol) × (1.00 mol/L) = 58.44 g/L
