A walkthrough, end to end.
- 1
Enter any two of molarity, moles, or volume.
- 2
The third is computed.
- 3
Optional: enter molar mass to derive grams of solute needed.
Molarity
M = n / V. Mass = n × molar mass.
What you can do with this.
Lab solutions
Prepare a 0.1 M NaCl solution exactly.
Buffer prep
Compute moles needed for buffer recipes.
Titration
Solve concentration from volume × molarity.
Chemistry homework
Verify M = n/V problems instantly.
Pharmaceutical formulation
Convert mass to moles using molar mass.
Frequently asked.
Molarity = mol/L solution. Molality = mol/kg solvent.
Convert: 1000 mL = 1 L.
