Butane gas (C4H10) is used as fuel for portable gas stoves. Calculate the volume (in L) of CO2 gas formed at STP when butane is combusted in a 10.0 L reaction vessel with a pressure of 3.15 atm at 25.0°C. The balanced reaction equation is as follows:
2 C4H10(g) + 13 O2(g) → 8 CO2(g) + 10 H2O(l)
(a) 28.9 L
(b) 703 L
(c) 115 L
(d) 352 L
