Avogadro Calculator

Avogadro Calculator is a fast, clean chemistry conversion tool that makes stoichiometry simple.

Enter any two of the four values — Mass (g), Moles (mol), Molar Mass (g/mol), or Particles — and instantly get the other two calculated using Avogadro's number (6.02214076 × 10²³ mol⁻¹).

✦ FEATURES
• Convert between mass, moles, molar mass, and number of particles
• Built-in periodic table — tap any element to auto-fill its molar mass
• Real-time calculations as you type
• Clean, modern dark theme interface
• Scientific notation display for large numbers
• Clear All button to reset instantly

✦ PERFECT FOR
• Chemistry students (AP, IB, college)
• Lab work and homework
• Quick stoichiometry calculations
• Anyone working with Avogadro's number

✦ HOW IT WORKS
1. Enter any two values (mass, moles, molar mass, or particles)
2. The other two values are calculated automatically
3. Use the Periodic Table button to look up molar masses

No ads. No tracking. Just a clean, fast chemistry calculator.
