Molality Calculator
🧪 Solutions & Molarity. Use the Molality formula to find molality, solute, solvent: pick the value you want, type the others, and the answer updates as you go.
Molality0.5 mol/kg
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| Molality | mol/kg |
| Solute | mol |
| Solvent | kg |
Worked example
Find the molality when Solute = 0.1 mol, Solvent = 0.2 kg.
Using m = nsolutemsolvent: Molality = 0.5 mol/kg.
Frequently asked questions
What is the formula for Molality?
m = nsolutemsolvent.
What do the letters stand for, and what units are used?
Molality in mol/kg, Solute in mol, Solvent in kg.
How do you calculate molality?
Put the values into m = nsolutemsolvent. For example, with Solute = 0.1 mol, Solvent = 0.2 kg, molality = 0.5 mol/kg.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (molality, solute, solvent) and fill in the others: it rearranges the formula for you.
