Approx. #556*g# water are evolved...

Explanation:

We address the stoichiometric equation....

#C_2H_6(g) + 7/2O_2(g) rarr2CO_2(g) + 3H_2O#

And so if #20.6*mol# carbon dioxide is evolved, there is an equivalent quantity of #3/2xx20.6*mol# water evolved...i.e. #30.9*mol# with respect to water.

All we do is address the stoichiometry of the reaction appropriately.....
