A technical article on diesel engines gives the energy available from diesel fuel in two forms: $41.8\,\text{MJ kg}^{-1}$ and $34.9\,\text{GJ m}^{-3}$. What is the density of diesel fuel?
- A$8.35 \times 10^2\,\text{kg m}^{-3}$
- B$1.20 \times 10^3\,\text{kg m}^{-3}$
- C$8.35 \times 10^5\,\text{kg m}^{-3}$
- D$1.20 \times 10^6\,\text{kg m}^{-3}$
