represent the ratio of the number of moles of a reactant and the number of moles of a product. Sucrose alone cannot have a mole ratio since no chemical reaction is given - it cannot have a mole ratio to itself.

For example, if you take sucrose's combustion reaction

##C_12H_22O_11 + 12O_2 -> 12CO_2 + 11H_2O##

You can say that the reaction shows a ##1:12## mole ratio between sucrose and carbon dioxide (##CO_2##) and a ##1:11## mole ratio between sucrose and water (##H_2O##).
