Calculators

Calculates the total pressure of a gas mixture using Dalton's Law of Partial Pressures.

Calculates the pressure, volume, temperature, or number of moles of a real gas using the van der Waals equation of state.

This calculator applies the combined gas law to determine the final pressure, volume, or temperature of a gas, given its initial conditions and changes in two of the three properties (pressure, volume, and temperature). The combined gas law is expressed as: (P1 * V1) / T1 = (P2 * V2) / T2

Calculates the partial pressure of a gas in a mixture using Dalton's Law of Partial Pressures.

Calculates the electromotive force (EMF) of an electrochemical cell using the standard reduction potentials of the half-cells.

Calculates the degrees of freedom (F) in a system using Gibbs' Phase Rule: F = C - P + 2, where C is the number of components and P is the number of phases.

Calculates the mass percentage of a component in a mixture.

Calculates the pH, pKa, or the ratio of acid and conjugate base concentrations using the Henderson-Hasselbalch equation. This equation is commonly used in chemistry, biology, and medicine to estimate the pH of a buffer solution.

This calculator helps determine the name of an ionic compound based on the cation and anion provided.

Calculates the molar mass (molecular weight) of a chemical compound or element. Enter the chemical formula to calculate its molar mass.
