How to Calculate the Molar Mass of Sucrose (C12H22O11)

To calculate the molar mass of sucrose (C₁₂H₂₂O₁₁), you need to sum the atomic masses of all the atoms in the molecule. Here’s how you can do it:

1. Identify the number of each type of atom in the molecule:
   • Carbon (C): 12 atoms
   • Hydrogen (H): 22 atoms
   • Oxygen (O): 11 atoms
2. Find the atomic mass of each element:
   • Carbon (C): 12.01 g/mol
   • Hydrogen (H): 1.008 g/mol
   • Oxygen (O): 16.00 g/mol
3. Calculate the total mass for each element:
   • Carbon: 12 atoms × 12.01 g/mol = 144.12 g/mol
   • Hydrogen: 22 atoms × 1.008 g/mol = 22.176 g/mol
   • Oxygen: 11 atoms × 16.00 g/mol = 176.00 g/mol
4. Sum the masses of all the elements:
   • 144.12 g/mol (Carbon) + 22.176 g/mol (Hydrogen) + 176.00 g/mol (Oxygen) = 342.296 g/mol

Therefore, the molar mass of sucrose (C₁₂H₂₂O₁₁) is approximately 342.30 g/mol.
