Ch 3: Mole ratio for a compound The chemical formula tells us the mole ratio. CO 2 = 1 CO 2 molecule : 1 C atom : 2 O atoms. Ch 4: Mole ratio for a reaction The balanced chemical reactions tells us. C 12 H 22 O 11 + 12 O 2 12 CO 2 + 11 H 2 O 1 C 12 H 22 O 11 molecule: 12 O 2 molecules : 12 CO 2 molecules : 11 H 2 O molecules. Applications of the mole ratio concept grams <--> moles <--> moles <--> grams
