Calculators

Calculates the normality of a solution, which represents the number of equivalents of solute per liter of solution.

This calculator helps you convert between different concentration units, including molarity (mol/L) and percentage concentration (% w/v, % v/v, % w/w).

Calculates the estimated Total Dissolved Solids (TDS) in water based on Electrical Conductivity (EC). TDS represents the total concentration of dissolved substances in water, typically expressed in parts per million (ppm) or milligrams per liter (mg/L).

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

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

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

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

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 pH, pKa, or the ratio of acid and conjugate base concentrations using the Henderson-Hasselbalch equation. This equation is commonly used in chemistry, biology, and medicine to estimate the pH of a buffer solution.

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.
