A typical fat in the body is glyceral trioleate, C57H104O6. When it is metabolized in the body, it combines with oxygen to produce carbon dioxide, water, and 3.022 x 10^4 kJ of heat per mole of fat.

B)How many kilokoules of energy must be evolved in the form of heat if you want to get rid of five pounds of this fat by combustion?

In part A) i was asked to write a balanced equation.
It is: C57H104O6(S) + 80(O2)(G)--> 57CO2(G) + 52H20

what do i do?

    I would convert 5 pounds to grams, then convert to moles of fat.
    The reaction gives you 3.022 x 10^4 kJ/1 mol. Go from there.
