Hello,
Butane's combustion is:
Now the change in the Gibbs free energy for this reaction is computed via (don't forget that oxygen's Gibbs free energy of formation is 0 since it is an element):
Δ4Δ
5Δ
-Δ
Δ
Δ
Now, since the calculation is done for 1 mol of butane, the change in the Gibbs free energy for this fuel is:
Δ
Best regards.

Explanation:
Hello!
In this case, when determining empirical formulas by knowing the by-mass percent, we first must assume the percentages as masses so we can compute the moles of each element:
Now, for the determination of the subscript of each element in the empirical formula, we divide the moles by the fewest moles (P or N):
Thus, the empirical formula is:
