Mole Calculator Online
Convert quickly between mass, moles, and number of molecules with this comprehensive chemistry calculation tool. Our mole converter is essential for chemistry students solving stoichiometry problems, laboratory scientists preparing solutions, and researchers performing precise chemical analyses across educational and professional settings.
Formula:
Moles = Mass (g) / Molar Mass (g/mol)
Typical Use Cases
The mole calculator is a fundamental tool in chemistry for converting between different quantitative measures of substances. Students use the calculator to solve stoichiometry problems, where they need to determine the amounts of reactants or products in chemical reactions. Scientists and laboratory technicians rely on mole calculations when preparing solutions of specific concentrations.
In research and industry, mole calculations are essential for determining exact quantities needed for reactions, analyzing chemical compositions, and ensuring proper ratios of elements in compounds. The mole concept serves as a bridge between the microscopic world of atoms and molecules and the macroscopic world of measurable quantities.
Formula
- Mass to Moles: n = m / M (where n is moles, m is mass in grams, and M is molar mass in g/mol)
- Moles to Particles: N = n ร NA (where N is number of particles and NA is Avogadro's number, 6.022 ร 1023 particles/mol)
- Particles to Moles: n = N / NA
- Moles to Mass: m = n ร M
