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.

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

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.

Determines the electron configuration and number of valence electrons for a given element based on its atomic number.

Calculates the average atomic mass of an element based on the masses and natural abundances of its isotopes.

Defines different heart rate zones (e.g., Zone 1-5) based on maximum heart rate for training purposes.

Converts a number of steps into an approximate distance in miles.

Converts a number of steps into an approximate distance in kilometers.
