Which expression gives the mass, in g, of ethanol required to produce 683.5 kJ of heat upon complete combustion?

(M_r for ethanol = 46.0, \(\Delta H_c^\theta  =  - 1367{\text{ kJ}}\,{\text{mo}}{{\text{l}}^{ - 1}}\))

A.     \(\frac{{683.5}}{{1367 \times 46.0}}\)

B.     \(\frac{{1367}}{{683.5 \times 46.0}}\)

C.     \(\frac{{683.5 \times 46.0}}{{1367}}\)

D.     \(\frac{{1367 \times 46.0}}{{683.5}}\)

C
