The table shows the percentages of hydrocarbons that are found in a sample of crude oil. hydrocarbons percentage paraffins 30 naphthenes 49 aromatics 15 asphaltics 6 based on the given information, what is the best classification for this sample of crude oil?

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
