What is the ratio of hydrogen atoms to oxygen atoms in a carbohydrate? - Leaving Cert Biology - Question d - 2004

In carbohydrates, the general formula is given as Cₓ(H₂O)ᵧ. This indicates that for every carbon atom, there are typically two hydrogen atoms and one oxygen atom. Therefore, the ratio of hydrogen atoms to oxygen atoms is:

rac{H}{O} = rac{2H}{O} = 2:1

Thus, the ratio of hydrogen to oxygen atoms in a carbohydrate is 2:1.
