आणविक भार क्या है?
Molecular weight (also called molar mass) is the total mass of one mole of a compound, calculated by summing the atomic weights of every atom in its chemical formula. It is expressed in grams per mole (g/mol) and is fundamental to converting between mass and moles in stoichiometry, solution preparation, and analytical chemistry.
FORMULA
आणविक वजन: MW = Σ (Atomic Weight × Count)
Mass %: % = (Element Mass / MW) × 100
Supported Formula Formats

Common Molecular Weights
• H₂O (पानी) = 18.015 ग्राम/मोल
• CO₂ (कार्बन डाइऑक्साइड) = 44.009 g/mol
• NaCl (टेबल सॉल्ट) = 58.443 ग्राम/मोल
• C₆H₁₂O₆ (ग्लूकोज) = 180.156 g/mol
• Ca(OH)₂ (कैल्शियम हाइड्रॉक्साइड) = 74.093 g/mol
• C₈H₁₀N₄O₂ (कैफीन) = 194.190 g/mol
• C₂H₅OH (इथेनॉल) = 46.069 ग्राम/मोल
महत्वपूर्ण नोट्स
- Element symbols are case-sensitive: Na (sodium) vs NA (invalid).
- Parentheses must be properly balanced.
- परमाणु भार IUPAC मानक मान हैं।
- Mass percentages always sum to 100%.
