alleryStart learning →A bomb calorimeter (20.7 kJ/K) warms 1 K when 1 g of graphite burns. What is ΔU per mole?
A-1.7 kJ/mol
B+248 kJ/mol
C-248 kJ/mol
D-20.7 kJ/mol
Answer & Solution
Correct answer: C. -248 kJ/mol
Heat released per gram is 20.7 kJ, and 12 g per mole gives about -248 kJ/mol, with ΔH equal since Δng = 0.
