Calculating the Formula Mass
Determining the formula mass of C12H24O6 requires knowledge of the atomic masses of its constituent elements. Each element’s atomic mass is a fundamental constant used to calculate the total molecular weight.
- Carbon (C):
Atomic mass ≈ 12.01 g/mol - Hydrogen (H):
Atomic mass ≈ 1.008 g/mol - Oxygen (O):
Atomic mass ≈ 16.00 g/mol
Using these values, the total formula mass is computed by multiplying the number of atoms of each element by their respective atomic masses and summing the results:
- Carbon contribution: 12 × 12.01 g/mol = 144.12 g/mol
- Hydrogen contribution: 24 × 1.008 g/mol = 24.192 g/mol
- Oxygen contribution: 6 × 16.00 g/mol = 96.00 g/mol
Total formula mass: 144.12 + 24.192 + 96.00 = 264.312 g/mol
