See the explanation.

Explanation:

The ratio of hydrogen to oxygen in carbohydrates is 2:1, the same as water. So it's as if the carbon atoms are combined with water. For monosaccharides the general formula is "CH"_2"O".

Monosaccharides

"C"_6"H"_12"O"_6" (glucose, fructose, galactose)

"C"_5"H"_10"O"_5" (ribose)

Disaccharides

"C"_12"H"_22"O"_11" (sucrose, maltose, lactose)

Polysaccharides

("C"_6"H"_10"O"_5")"_n" (starch and cellulose)

"C"_24"H"_42"O"_21" (glycogen)
