Moles in a Solution Calculator
⚗ Moles & Stoichiometry. Use the Moles in a solution formula to find amount, concentration, volume: pick the value you want, type the others, and the answer updates as you go.
V in dm³: divide cm³ by 1000.
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 |
|---|---|
| Amount | mol |
| Concentration | mol/dm³ |
| Volume | cm³ |
Worked example
Find the amount when Concentration = 0.1 mol/dm³, Volume = 25 cm³.
Using n = c × V: Amount = 0.0025 mol.
Frequently asked questions
What is the formula for Moles in a solution?
n = c × V. V in dm³: divide cm³ by 1000.
What do the letters stand for, and what units are used?
Amount in mol, Concentration in mol/dm³, Volume in cm³.
How do you calculate amount?
Put the values into n = c × V. For example, with Concentration = 0.1 mol/dm³, Volume = 25 cm³, amount = 0.0025 mol.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (amount, concentration, volume) and fill in the others: it rearranges the formula for you.
