Calculators

Calculates the boiling point elevation of a solution using the ebullioscopic constant, molality, and van't Hoff factor.

Calculates the remaining amount of a substance after a certain period, given its initial amount and half-life.

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

Calculates the fractional surface coverage (θ) based on the Langmuir adsorption isotherm model, which describes the equilibrium between adsorption and desorption of a gas on a solid surface.

This calculator determines the molecular SO2 content in homemade wines, helping winemakers achieve optimal wine preservation. It supports different wine types and pH levels.

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

Calculates the partial pressure of a gas in a 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 converts between the equilibrium constants Kp (expressed in terms of partial pressures) and Kc (expressed in terms of concentrations).

Calculates the pressure or temperature of a gas under constant volume conditions using Gay-Lussac's Law (P1/T1 = P2/T2).
