How to use this tool?
This calculator provides four essential AP Chemistry tools. Follow the steps below for each function.
1. Molar Mass
- Enter a chemical formula (e.g., H2SO4) in the text field.
- Click Calculate.
- The result shows the molar mass in g/mol.
- Note: Use standard element symbols (e.g., Na for sodium).
2. Dilution
- Enter Initial Concentration (M), Initial Volume (L), and Final Volume (L).
- All values must be positive numbers.
- Click Calculate to get the Final Concentration (M) using C₁V₁ = C₂V₂.
3. pH Calculator
- Enter the hydronium ion concentration [H₃O⁺] in M (must be positive).
- Click Calculate pH to get the pH value (pH = -log₁₀[H₃O⁺]).
4. Ideal Gas Law
- Enter Pressure (atm), Volume (L), Moles (mol), and Temperature (K).
- All values must be positive.
- Click Calculate to see both sides of PV = nRT and their difference.
- Note: Uses R = 0.082057 L·atm/(mol·K). Ensure units match (atm, L, mol, K).

Frequently Asked Questions
Enter a chemical formula like H2SO4 and click Calculate. The calculator uses standard atomic masses to compute the molar mass in g/mol.
The dilution calculator uses C1V1 = C2V2, where C1 is initial concentration, V1 initial volume, and V2 final volume. It solves for C2.
pH is calculated as -log10([H3O+]), where [H3O+] is the hydronium ion concentration in mol/L.
