Calculators

Calculates the hydrogen ion concentration ([H+]) of a solution given its pH value. This is a fundamental calculation in chemistry for understanding acidity and basicity.

Calculates the alligation ratios needed to mix two solutions of different concentrations to achieve a desired intermediate concentration.

Calculates the rate constant of a chemical reaction using the Arrhenius equation, which relates the rate constant to the activation energy, temperature, and pre-exponential factor.

Converts parts per million (ppm) to molarity (mol/L) for solutions. This calculation requires the solute's molecular weight and the solution's density.

Calculates the number of moles in a given mass of a substance using its molecular weight.

Calculates the molar mass (molecular weight) of a chemical compound or element. Enter the chemical formula to calculate its molar mass.

Calculates the mass percentage of a component in a mixture.

Calculates the mole fraction of a substance in a mixture using two different methods: either by providing the number of moles of each substance or by providing the mass of each substance and their respective molar masses.

Calculates the percent ionic character of a chemical bond based on the electronegativity difference between two atoms.

Calculates the molality of a solution given the moles of solute and the mass of the solvent.
