* C: Represents the element carbon.
* 6: Indicates there are 6 carbon atoms in each molecule of citric acid.
* H: Represents the element hydrogen.
* 8: Indicates there are 8 hydrogen atoms in each molecule of citric acid.
* O: Represents the element oxygen.
* 7: Indicates there are 7 oxygen atoms in each molecule of citric acid.
Therefore, the formula C6H8O7 tells us that one molecule of citric acid contains 6 carbon atoms, 8 hydrogen atoms, and 7 oxygen atoms.
