Butane (C4H10) undergoes combustion in excess oxygen to generate gaseous carbon dioxide and water.Given H°f [C4H10(g) ] = -124.7 kJ/mol, H°f[CO2(g) ] = -393.5 kJ/mol, H°f[H2O(g) ] = -241.8 kJ/mol, how much energy is released (kJ) when 8.30 g of butane is burned?
A) 22,100 kJ
B) 2,658.3 kJ
C) 379 kJ
D) 759 kJ
E) 2,910 kJ
