## Molecular Weight Calculation
The molecular weight (molar mass) of a compound is the sum of the atomic weights of all atoms in its molecular formula.
### Formula
**MW = sum(n_i × AW_i)**
where n_i is the number of atoms of element i and AW_i is the standard atomic weight. Standard atomic weights: C = 12.011, H = 1.008, O = 15.999, N = 14.007, S = 32.065 g/mol.

Esempio Risolto
Calculate the molecular weight of glucose (C6H12O6).
- C contribution: 6 × 12.011 = 72.066
- H contribution: 12 × 1.008 = 12.096
- O contribution: 6 × 15.999 = 95.994
- MW = 72.066 + 12.096 + 95.994 = 180.156 g/mol
