What each letter means
| Quantity | Unit |
|---|---|
| Molarity | mol/L |
| Solute | mol |
| Volume | L |
Worked example
Find the molarity when Solute = 0.1 mol, Volume = 0.2 L.
Using M = nsoluteVsolution: Molarity = 0.5 mol/L.
Frequently asked questions
What is the formula for Molarity?
M = nsoluteVsolution.
What do the letters stand for, and what units are used?
Molarity in mol/L, Solute in mol, Volume in L.
How do you calculate molarity?
Put the values into M = nsoluteVsolution. For example, with Solute = 0.1 mol, Volume = 0.2 L, molarity = 0.5 mol/L.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (molarity, solute, volume) and fill in the others: it rearranges the formula for you.
