Calculators

Calculates the pH of a solution based on hydrogen ion concentration ([H+]), or the acid dissociation constant (Ka) and solution concentration.

Calculates the dilution factor, final volume, initial volume, or final concentration based on the given inputs. Dilution is the process of reducing the concentration of a solute in a solution, usually simply by mixing with more solvent.

Calculates the activation energy of a chemical reaction using the Arrhenius equation. This calculator helps determine the minimum energy required for a reaction to occur.

Calculates the required volume of diluent to add to a dry ingredient (drug) to achieve a desired concentration, and the resulting mass of the drug in a given volume.

Calculates the vapor pressure of an ideal solution using Raoult's Law. It can also determine the vapor pressure and mole fraction of a pure solvent in a solution.

Calculates the mass/volume percent, mass percent, and volume percent of a solution.

Calculates the actual yield of a chemical reaction, given the theoretical yield and percent yield.

Calculates the molarity of an unknown solution using titration data.

Calculates the atom economy of a chemical reaction, which is a measure of the proportion of reactant atoms that become incorporated into the desired product. It helps assess the efficiency and waste generated in a chemical process.

Calculates the bond order of a molecule based on the number of bonding and antibonding electrons or from the number of bonds between two atoms.
