Molecular Mass Of Glucose
Molecular Formula of Glucose
Before we explore the molecular mass of C6H12O6, it’s essential to understand its molecular formula. Glucose has the chemical formula C6H12O6. This formula represents the number of carbon (C), hydrogen (H), and oxygen (O) atoms in a single glucose molecule.
Calculating Molecular Mass
The molecular mass of a compound is the sum of the atomic masses of all the constituent atoms in its molecular formula. To calculate the molecular mass of C6H12O6, we add the atomic masses of the individual elements:
- Carbon (C) has an atomic mass of approximately 12.01 atomic mass units (amu).
- Hydrogen (H) has an atomic mass of approximately 1.01 amu.
- Oxygen (O) has an atomic mass of approximately 16.00 amu.
Now, let’s calculate the molecular mass of C6H12O6:
Molecular mass of glucose = (6 × C) + (12 × H) + (6 × O) Molecular mass of C6H12O6 ≈ (6 × 12.01 amu) + (12 × 1.01 amu) + (6 × 16.00 amu) Molecular mass of glucose ≈ 72.06 amu + 12.12 amu + 96.00 amu Molecular mass of glucose ≈ 180.18 amu
Rounded to two decimal places, the molecular mass of C6H12O6 is approximately 180.18 amu or 180.18 g/mol (grams per mole).
