Look at your combustion equation....

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

Explanation:

And clearly, GIVEN the equation, if I combust a #10*L# volume of ethane, I will be requiring a #35*L# volume of dioxygen gas... Do you agree? And if I combust a #10*L# volume of ethane, then what volume of carbon dioxide will I generate (take that atmosphere!)? You should be able to answer pdq.

That they quoted the temperature was an attempt to distract you....we assume that the reactants were also at this temperature. The question is poorly specified.
