Molarity Calculator

The calculators on this page are independent and can be used in any order.

1. Mass from Volume & Concentration

Concentration: M [molar, mole/liter] mM [millimolar, millimole/liter] µM [micromolar, micromole/liter] nM [nanomolar, nanomole/liter]

Formula Weight (g/mol):

Volume: L [liter] mL [milliliter]

2. Volume from Mass & Concentration

Mass: gram [g] milligram [mg]

Formula Weight (g/mol):

Concentration: M [molar, mole/liter] mM [millimolar, millimole/liter] µM [micromolar, micromole/liter] nM [nanomolar, nanomole/liter]

3. Molarity from Mass & Volume

Mass: gram [g] milligram [mg]

Formula Weight (g/mol):

Volume: L [liter] mL [milliliter]

4. Dilute a Stock Solution

Stock Concentration: M [molar, mole/liter] mM [millimolar, millimole/liter] µM [micromolar, micromole/liter] nM [nanomolar, nanomole/liter]

Desired Concentration: M [molar, mole/liter] mM [millimolar, millimole/liter] µM [micromolar, micromole/liter] nM [nanomolar, nanomole/liter]

Desired Volume: L [liter] mL [milliliter]
