If we set up a bomb calorimetry experiment to determine the molar enthalpy of combustion of ethene (C2H4) using 1 L of water as our heat sink, 2.805 g of ethene, and measure an initial and final temperature of 25.20◦C and 58.92◦C, respectively, what will be the experimentally determined molar enthalpy of combustion of ethene? Assume the density of water is 1.00 g · mL−1. Assume the calorimeter itself absorbs no heat. The specific heat capacity of water is 4.184 J · g −1 · K −1 .
1. −141.1 kJ · mol−1
2. −1, 411 kJ · mol−1
3. −14, 110 kJ · mol−1
4. −14.11 kJ · mol−1
5. −141, 100 kJ · mol−1
