To find the total number of atoms in one molecule of maltose (C12H22O11), we need to count the individual atoms of each element in the chemical formula.
- Carbon (C): 12 atoms
- Hydrogen (H): 22 atoms
- Oxygen (O): 11 atoms
Now, we add them together:
12 (C) + 22 (H) + 11 (O) = 45 atoms
So the total number of atoms in one molecule of maltose is 45.
The correct answer is C. Forty-five.
