Well, first we specify that #1*mol# of Ideal Gas occupies a volume of #24.5*L#....at #1*atm# pressure and #298*K#....

Explanation:

We gots the stoichiometric equation....

#C_3H_8 + 5O_2(g) rarr 3CO_2(g) +4H_2O(l)#

Note that as written I gots the water as a LIQUID, but then again the question asked us to predict the volume that the carbon dioxide would occupy.

#"Moles of propane"-=(17.4*g)/(44.10*g*mol^-1)=0.395*mol#

And so volume of carbon dioxide evolved.....

#0.395*molxx3xx24.5*L*mol^-1=29.0*L#
