Calculators

Calculates the root-mean-square (RMS) speed of gas molecules based on temperature and molar mass.

Calculates the quantum yield of a photochemical process, which represents the efficiency of photon usage in initiating a specific reaction. It's the number of times a specific event occurs per photon absorbed.

This calculator converts between the equilibrium constants Kp (expressed in terms of partial pressures) and Kc (expressed in terms of concentrations).

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

Calculates the equilibrium constant (Kc) for a reversible chemical reaction based on the concentrations of reactants and products at equilibrium.

Calculates the carbon equivalent (CE) of steel, which indicates its weldability and other properties based on its chemical composition.

Calculates the reduction potential of an electrochemical cell using the Nernst Equation. This equation relates the reduction potential of an electrochemical reaction to the standard electrode potential, temperature, and activities of the chemical species undergoing reduction and oxidation.

Calculates the vapor pressure of water at a given temperature using various empirical formulas. The calculator provides results from the Antoine equation, the August equation, the Tetens equation, the Rankine equation, and the Clausius-Clapeyron equation. Note that these formulas are approximations and may have limitations in accuracy depending on the temperature range.

Convert moles of a substance to its mass using the molar mass of the substance.

Calculates the vapor pressure of a substance at a given temperature using the Clausius-Clapeyron equation. This calculator helps explore phase transitions and thermodynamics.
