Calcolatore di pH

Use the free online Calcolatore di pH tool. Fast, private and easy to use — runs entirely in your browser. Part of our Calcolatori di Chimica collection.

Calcolatore di Molarità

Solute mass (g) Molar mass (g/mol) Solution volume (L)

Find the molar concentration of a solution from solute mass, molar mass and volume.

Calcolatore di Diluizione

Stock concentration C1 Target concentration C2 Final volume V2

Use C1V1 = C2V2 to find how much stock solution and diluent a dilution needs.

Calcolatore di pH

[H+] concentration (mol/L) or pH (leave [H+] blank)

Convert between hydrogen-ion concentration, pH and pOH in both directions.

Calcolatore Legge dei Gas Ideali

Pressure P (atm) Volume V (L) — leave blank to solve Moles n Temperature T (K)

Solve PV = nRT for the missing variable using R = 0.082057 L·atm/mol·K.

Convertitore Grammi-Moli

Molar mass (g/mol) Mass (g) or Moles (leave mass blank)

Convert between grams and moles of any substance using its molar mass.

Calcolatore Legge Combinata dei Gas

Initial pressure P1 Initial volume V1 Initial temperature T1 (K) Final volume V2 (or leave blank) Final pressure P2 (or leave blank) Final temperature T2 (K)

Apply P1V1/T1 = P2V2/T2 to find the final pressure or volume of a gas.

Calcolatore di Emivita

Initial amount Half-life Elapsed time (same unit)

Find how much of a decaying substance remains after any elapsed time.

Calcolatore Percentuale Soluzione

Solute mass (g) Solution volume (mL)

Express a solution strength as % w/v and grams per litre.
