(b) When a sample of C2H5OH was combusted, the volume of CO2(g) produced was 18.0 L when measured at
21.7°C and 1.03 atm.
(i) Determine the number of moles of CO2(g) that was produced.
(ii) Determine the volume of C2H5OH(1), in mL, that was combusted to produce the volume of CO2(g)
collected. (The density of C2H5OH() is 0.79 g/mL.)
(iii) Determine the amount of heat, in KJ, that was released by the combustion reaction.
