Answer:
9517.2 lbm
Explanation:
Electricity consumption = 14000 kWh/year
Fuel consumption = 900 gal/year
Amount of CO₂ produced per gallon = 26.4 lbm/gal
Amount of CO₂ produced per kWh = 1.54 lbm/kWh
Amount of CO₂ produced in one year

Reduction would be

The reduction in the amount of CO₂ produced is 9517.2 lbm

Hope it helped!
Convert mL to gallons as follows:
355 mL = 0.355 L
0.355 L * (1 gal/3.785 L) = 0.0938 gallons
The equivalent km covered would be
57miles/gal * 0.0938 gal * (1.61 km/ 1 mile) = 8.61 kilometers
I hope I was able to help you. Have a good day!
