🧪 Chemistry Tips & Concepts
Mole Concept
One mole contains exactly 6.02214076×10²³ elementary entities (Avogadro's number).
Conversion Formula
Moles = Mass (g) / Molar Mass (g/mol)
Mass = Moles × Molar Mass
Molar Mass
Calculate molar mass by summing the atomic masses of all atoms in the chemical formula.
Common Mistakes
Ensure correct chemical formulas and watch for diatomic elements (H₂, N₂, O₂, F₂, Cl₂, Br₂, I₂).
Significant Figures
Your answer should have the same number of significant figures as your least precise measurement.
Practical Applications
Used in stoichiometry, solution preparation, and chemical reaction calculations.
Note: This calculator uses standard atomic weights from IUPAC. For precise laboratory work, always use the most current atomic weights and consider isotopic composition when extreme accuracy is required.
