🧪 Molarity Calculator
Calculate molarity, moles, or volume (M = n/V)
Enter any two values to calculate the third (M = n / V).
How Molarity Calculation Works
Formula
M = n / V (Molarity = moles / liters)
- 1Enter any two of: moles of solute, volume in liters, or molarity.
- 2The calculator solves for the missing value.
- 3Molarity = moles / volume (M = n/V).
- 4Moles = molarity × volume (n = MV).
- 5Volume = moles / molarity (V = n/M).

Frequently Asked Questions
What is molarity?
Molarity (M) is the number of moles of solute per liter of solution. A 1M solution contains 1 mole of solute dissolved in enough solvent to make 1 liter of solution.
How is molarity different from molality?
Molarity uses liters of solution (solute + solvent), while molality uses kilograms of solvent only. Molality doesn't change with temperature since mass doesn't expand.
How do I prepare a solution of specific molarity?
Calculate moles needed (M × V), convert to grams using molar mass, weigh that amount, dissolve in solvent, then add solvent to reach the final desired volume.
