Liquid methanol (CH
OH) is used as an alternative fuel in truck engines. When a 0.150 g sample
of methanol was burned in a calorimeter, open to
the atmosphere, the temperature increased 1.52 ºC.
The heat capacity of the calorimeter was 1.97 kJ
/ ºC. The products of the reaction were carbon

) = -393.5 kJ/mol and water vapour,
