How to do this
When 0.100 g of graphite is burned com-
pletely in a bomb calorimeter (heat capacity
= 3.344 kJ/°C), containing 3000 g of water, a
temperature rise of 0.21°C is observed. What
is AE for the combustion of graphite? The
specific heat of liquid water is 4.184 J/g °C.
1. ΔΕ = +3.34 kJ/mol
2. ΔΕ = -40.1 kJ/mol
3. AE = -285. kJ/mol
4. AE = -3.34 kJ/mol
5. AE = -401.0 kJ/mol
