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

Converts between moles, mass, and molecular weight.

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

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.

Calculates the molar mass of a gas using the ideal gas law (PV = nRT), where molar mass (M) = mass / moles. This calculator rearranges the ideal gas law to solve for molar mass: M = (mass * R * temperature) / (pressure * volume).

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.

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