A 5.00 g sample of ethanol undergoes combustion in a container submerged in 2L of room temperature water. The enthalpy of combustion of ethanol (C₂H₆O) is -1367 kJ/mol. If the container absorbs 2.30 kJ for every °C temperature change (heat capacity of container = 2.30 kJ/mol), what is the final temperature of the water?
a) 25.7 °C
b) 31.3 °C
c) 37.8 °C
d) 42.4 °C
