How to Use the Molecular Weight Calculator:

  1. Element Selection:
    • Begin by choosing the first element in your chemical formula.
    • Input the quantity of that atom.
  2. Repeat the Process:
    • Continue this process for each element in your formula.
  3. View Results:
    • Your molecular weight results are displayed in unified atomic mass units ([u] = [Da]) at the bottom of our user-friendly calculator. ⚛️
    Both the MW and the chemical formula are presented for your convenience.

Molecular Weight vs. Molar Mass:

While these terms may seem interchangeable, they carry nuanced differences:

  • Molecular Weight/Molecular Mass:
    • Describes the mass of a single molecule in daltons (Da) or unified atomic mass units (u).
    • Example: Molecular mass of water is 18 u.
  • Molar Mass:
    • Represents the mass of 1 mole of a substance in grams per mole (g/mol).
    • 1 mole comprises precisely 6.02214076 * 10²³ molecules.
    • Example: Molar mass of water is 18 g/mol.

How to Calculate Molecular Weight:

Let’s demystify the process with a practical example: Calculating the molecular mass of glucose.

  1. Chemical Formula of Glucose:
    • C₆H₁₂O₆
  2. Transform the Formula:
    • MW = (6 * C) + (12 * H) + (6 * O)
  3. Atomic Mass Lookup:
    • Refer to the periodic table for atomic masses.
    • C – 12 u; H – 1 u; O – 16 u.
  4. Calculation:
    • MW = (6 * 12u) + (12 * 1u) + (6 * 16u)
    • MW = 180 u

✅ Success! The molecular weight of glucose is 180 u.

Periodic Table Curiosities:

Delve into the wonders of the periodic table:

  • The periodic table boasts 118 elements, with the latest additions in 2016.
  • Noteworthy elements named after American figures include Lawrencium (103), Seaborgium (106), Tennessine (117), and Californium (98).
  • Fun fact: Americium was named after both American continents, contrary to popular belief.
