Would it not be approx. 12 moles given complete combustion?

Explanation:

Ethane combusts completely according to the stoichiometric equation...

#C_2H_6(g) +7/2 O_2(g) rarr 2CO_2(g) + 3H_2O(l) + Delta#

And so each mole of ethane gives rise to TWO MOLE carbon dioxide... And so if #5.95*mol# ethane were combusted...

We get #underbrace(2xx5.95*mol*CO_2)_"combustion product"=??*mol#

What mass is this?
