Answer:
32.97 tons of CO2 per day.
Step-by-step explanation:
From the question given above, the following were obtained:
Power plant burns = 12 tons of coal per day
1 ton of coal = 7327 kWh
CO2 emitted = 0.75 pound per kWh
Tons of CO2 emitted per day =?
Next, we shall convert 0.75 pound to ton.
This can be obtained as follow:
2000 pounds = 1 ton
Therefore,
0.75 pound = 0.75 pound/2000 pounds × 1 ton
0.75 pound = 3.75×10¯⁴ ton
Therefore, 0.75 pound is equivalent 3.75×10¯⁴ ton.
From the above, we can say that CO2 is emitted at 3.75×10¯⁴ ton per kWh.
Next, we shall determine the electricity generated per day.
This can be obtained as follow:
1 ton of coal = 7327 kWh of electricity
Therefore,
12 tons of coal = 12 × 7327
12 tons of coal = 87924 kWh of electricity.
Therefore, the plant produces 87924 kWh of electricity per day.
Finally, we shall determine the tons of CO2 emitted per day as follow:
1 kWh of electricity emitts 3.75×10¯⁴ ton of CO2.
Therefore, 87924 kWh of electricity will emitt = 87924 × 3.75×10¯⁴ = 32.97 tons of CO2 per day.
From the calculations made above, the pant emitts 32.97 tons of CO2 per day.
