The Combustion of Butane in Oxygen at 298 K Is $\Delta_{T} H_{298}^{\theta}$

Multiple Choice

The combustion of butane in oxygen at 298 K is given by the following thermochemical equation:
2 C₄H₁₀ (g) + 13 O₂ → 8 CO₂ (g) + 10 H₂O (l) $\Delta_{T} H_{298}^{\theta}$ = -2878 kJ mol^-1. How much heat energy (in kJ) is supplied when 775 g of butane burn in a plentiful supply of air so that combustion is complete?

A) 38370.
B) 2878.
C) 2230.45
D) 2230450.
