Defining Molecular Weight: The Sum of Atomic Weights
Every molecule is composed of atoms, the basic building blocks of matter. The molecular weight, also known as molar mass, is simply the sum of the atomic weights of all the atoms in a molecule. Just as the weight of a bag of groceries is the combined weight of its individual items, the molecular weight of sucrose represents the cumulative weight of its constituent atoms.
Calculating Sucrose’s Molecular Weight
Sucrose, with the molecular formula C₁₂H₂₂O₁₁, is composed of 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms. To calculate its molecular weight, we add up the atomic weights of these elements:
- Carbon (C): 12 x 12.011 g/mol = 144.132 g/mol
- Hydrogen (H): 22 x 1.008 g/mol = 22.176 g/mol
- Oxygen (O): 11 x 16.000 g/mol = 176.000 g/mol
Total Molecular Weight of Sucrose: 144.132 g/mol + 22.176 g/mol + 176.000 g/mol = 342.308 g/mol
Hence, the molecular weight of sucrose is approximately 342.3 g/mol, indicating that every mole of sucrose weighs 342.3 grams.
