Calculators

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

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

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

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.

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

Calculates the amounts of concentrate and water needed to achieve a specific dilution ratio.

Calculates the theoretical yield of a chemical reaction based on the moles of the limiting reactant and the stoichiometry of the reaction.

Calculates the Index of Hydrogen Deficiency (IHD), also known as the Degree of Unsaturation, which indicates the number of rings and/or pi bonds in a molecule.

Calculates the entropy change for ideal gases under isothermal conditions and for chemical reactions using the Gibbs free energy formula.
