How to use this tool?
This calculator computes two key AP Chemistry values: molarity and, optionally, the pH of a weak acid.
- Enter Moles of Solute (mol) – The amount of substance dissolved.
- Enter Volume of Solution (L) – Must be in liters. Use metric units only.
- Optional: Enter Ka and Acid Concentration (M) – If you want pH, provide both the acid dissociation constant (Ka) and the weak acid’s molarity.
- Click Calculate.
Results: You’ll see the molarity (M) and, if applicable, the pH. A step-by-step breakdown shows the formula used.
Tip: Leave Ka and Acid Concentration blank if you only need molarity.

Frequently Asked Questions
Molarity is calculated by dividing the moles of solute by the volume of solution in liters.
Yes, enter the Ka and initial acid concentration to compute the pH using the approximation formula.
Only molarity will be calculated. pH calculation requires both Ka and acid concentration.
