Calculators
Create and discover interactive calculators for various scenarios and measurements.
Equilibrium Constant Calculator
Calculates the equilibrium constant (Kc) for a reversible chemical reaction based on the concentrations of reactants and products at equilibrium.
Theoretical Yield Calculator
Calculates the theoretical yield of a chemical reaction based on the moles of the limiting reactant and the stoichiometry of the reaction.
Gibbs' Phase Rule Calculator
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.
Entropy Change Calculator
Calculates the entropy change for ideal gases under isothermal conditions and for chemical reactions using the Gibbs free energy formula.
Gay-Lussac's Law Calculator
Calculates the pressure or temperature of a gas under constant volume conditions using Gay-Lussac's Law (P1/T1 = P2/T2).
Mass to Moles Calculator
Calculates the number of moles from the mass of a substance and its molecular weight.
Combined Gas Law Calculator
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
Lattice Energy Calculator
Calculates the lattice energy of an ionic compound using a simplified Born-Landé equation. This calculator provides an estimate of the energy required to separate one mole of a solid ionic compound into gaseous ions.
Freezing Point Depression Calculator
Calculates the freezing point depression of a solution using the colligative properties formula. This calculator determines the change in freezing point when a nonvolatile solute is added to a solvent.
Molarity Calculator
Calculates the molarity of a solution given the number of moles of solute and the volume of the solution in liters. Also calculates mass from molarity, volume and molecular weight.
