Chemistry Formulas Used

  • Moles to Grams: mass (g) = moles (mol) × molar mass (g/mol)
  • Grams to Moles: moles (mol) = mass (g) ÷ molar mass (g/mol)
  • Number of Particles: particles = moles × 6.022 × 10²³
  • Molar Mass: molar mass (g/mol) = mass ÷ moles

15 Frequently Asked Questions (FAQs)

  1. What is a mole in chemistry?
    A mole represents 6.022 × 10²³ particles (atoms, molecules, ions).
  2. Why convert moles to grams?
    To measure substances in the lab, mass is more practical than counting individual molecules.
  3. What is molar mass?
    Molar mass is the mass of 1 mole of a substance, expressed in g/mol.
  4. Can I convert grams to moles?
    Yes, divide the mass by the substance’s molar mass.
  5. Why use this calculator instead of manual calculation?
    It reduces errors and provides quick, accurate conversions.
  6. Does it include common substances?
    Yes, H₂O, CO₂, NaCl, O₂, N₂, H₂, glucose, CaCO₃, H₂SO₄, and NH₃.
  7. Can I enter a custom substance?
    Yes, manually input the molar mass.
  8. How is the number of particles calculated?
