Calculators

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

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

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

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 percentage by mass of each element in a chemical compound.

This calculator helps determine the name of an ionic compound based on the cation and anion provided.
