Molecular Weight Calculator (Molar Mass)
The Molecular Weight Calculator (Molar Mass) is a powerful and user-friendly tool designed to compute the molecular weight (or molar mass) of chemical compounds based on their molecular formulas. This calculator is essential for students, chemists, researchers, and professionals working in chemistry-related fields who need quick and accurate molar mass calculations.
Key Features:
✅ Accurate Calculations – Uses standard atomic weights from IUPAC (International Union of Pure and Applied Chemistry) for precise results.
✅ Case-Sensitive Formula Parsing – Correctly interprets chemical formulas (e.g., H₂O, CO₂, C₆H₁₂O₆) with proper element symbols.
✅ Hydrated Compounds Support – Calculates molecular weights for hydrates (e.g., CuSO₄·5H₂O).
✅ Common Chemicals Database – Includes a dropdown list of frequently used inorganic and organic compounds for quick selection.
✅ Detailed Breakdown – Displays atomic composition, individual weights, and percentage contributions.
✅ User-Friendly Interface – Clean design with a gradient white and purple background for an engaging experience.
How It Works:
- Enter a molecular formula (e.g., H₂SO₄, C₆H₁₂O₆) or select a compound from the dropdown menu.
- Click "Calculate" to compute the molar mass.
- View the total molecular weight along with a detailed breakdown of each element's contribution.
Common Uses:
- Chemistry & Biochemistry Labs – Quickly determine molar masses for reactions and solutions.
- Academic Studies – Ideal for students learning stoichiometry and chemical calculations.
- Pharmaceutical & Industrial Applications – Essential for formulation and quality control.
Note:
- The terms "molecular weight" and "molar mass" are used interchangeably.
- Formulas must be case-sensitive (e.g., NaCl, not nacl).
- Supports parentheses for complex molecules (e.g., (NH₄)₂SO₄).
