To find the total number of atoms in one molecule of maltose (C₁₂H₂₂O₁₁), you can add the number of atoms of each element in the formula:
- Carbon (C): 12 atoms
- Hydrogen (H): 22 atoms
- Oxygen (O): 11 atoms
Now, add these together:
\[ 12 \text{ (C)} + 22 \text{ (H)} + 11 \text{ (O)} = 45 \]
Therefore, there are a total of 45 atoms in one molecule of maltose.
