Calculate Molecular Mass of Glucose C6H12O6 molecule.

To calculate the molecular mass of glucose (C₆H₁₂O₆), we need to sum the atomic masses of all the atoms in the molecule. The molecular formula of glucose shows that it contains 6 carbon (C) atoms, 12 hydrogen (H) atoms, and 6 oxygen (O) atoms.

Here’s how we calculate the molecular mass of glucose:

1. Find the Atomic Mass: Look up the atomic masses of each element from the periodic table. The atomic mass of carbon (C) is approximately 12.01 atomic mass units (amu), hydrogen (H) is approximately 1.01 amu, and oxygen (O) is approximately 16.00 amu.
2. Multiply by the Number of Atoms: Multiply the atomic mass of each element by the number of atoms of that element in the molecule.
   • Carbon (C): 6 atoms × 12.01 amu = 72.06 amu
   • Hydrogen (H): 12 atoms × 1.01 amu = 12.12 amu
   • Oxygen (O): 6 atoms × 16.00 amu = 96.00 amu
3. Add the Results: Add up the atomic masses of all the elements in the molecule.
   • 72.06 amu (C) + 12.12 amu (H) + 96.00 amu (O) = 180.18 amu

So, the molecular mass of glucose (C₆H₁₂O₆) is approximately 180.18 atomic mass units (amu). This value represents the mass of one glucose molecule in atomic mass units
