Here's how to figure out the number of atoms in a molecule of C6H12O6 (glucose):

* Count the subscripts: The subscripts in the chemical formula tell you how many of each type of atom are present.

* C6: 6 carbon atoms

* H12: 12 hydrogen atoms

* O6: 6 oxygen atoms

* Add them up: 6 + 12 + 6 = 24 atoms

Therefore, there are 24 atoms in one molecule of C6H12O6.
