What do coefficients tell you related to moles?

Formally the stoichiometric coefficients represent the number of moles of reactants and products....

Explanation:

...and this is why educators go to such lengths teaching stoichiometry, the principle that garbage in equals garbage out...

And so for say hexane combustion...

#C_6H_14(g) + 19/2O_2(g) rarr 6CO_2(g) + 7H_2O(l) + Delta#

One equiv of hexane reacts with #9*1/2# equiv dioxygen to give seven equiv of water, and six equiv of carbon dioxide, take that environment! And we could work out equivalent masses with the molar quantities of each reactant and product.
