Answer:
The additional carbon tax on each barrel is 0.394 ton x $250/ton = 98.5 $
Explanation:
A barrel volume is 159 L or 0.159 m³, which then can be converted to weight
Then we convert to mol,
The reaction for combustion of C₈H₁₈ is as below, each mol of C₈H₁₈ will generate 8 mol of CO₂,
So the mole of CO₂ generated is 1.12 x 10³ x 8 = 8.96 x 10³ mol
then convert to weight of CO₂,
Hence the additional carbon tax on each barrel is 0.394 ton x $250/ton = 98.5 $
