Answer:
Mole ratio for a compound
The chemical formula tells us the mole ratio.
CO2 = 1 CO2 molecule : 1 C atom : 2 O atoms.
Mole ratio for a reaction
The balanced chemical reactions tells us.
C12H22O11 + 12 O2 12 CO2 + 11 H2O
1 C12H22O11 molecule: 12 O2 molecules : 12 CO2
molecules : 11 H2O molecules.
Applications of the mole ratio concept
grams <--> moles <--> moles <--> grams
Explanation:
0.5 = 1/2 = 2/4 = 4/8 = 8/16 = 16/32…
0.75 = 3/4 = 6/8 = 12/16 = 24/32…
Then you can easily find the fractions in between are: 5/8, 9/16, 11/16, 17/32, 19/32, 21/32, 23/32...
