Calculators

Calculates the relative rate of effusion of two gases using Graham's Law, which states that the rate of effusion of a gas is inversely proportional to the square root of its molar mass.

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

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

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

Calculates the relationship between volume and temperature of a gas at constant pressure using Charles's Law: V1/T1 = V2/T2.

Calculates the Gibbs Free Energy (ΔG) of a reaction to determine its spontaneity. A negative ΔG indicates a spontaneous reaction, a positive ΔG indicates a non-spontaneous reaction, and a ΔG of zero indicates equilibrium.

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.

Calculates the percent yield of a chemical reaction, which represents the efficiency of the reaction. It compares the actual yield (amount of product obtained) to the theoretical yield (maximum possible amount of product).

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

Calculates the number of moles from the mass of a substance and its molecular weight.
