Grams of gasoline needed to raise level of CO in air.

In summary, the problem asks how many grams of gasoline must be burned in a garage with dimensions of 5x3x3 meters in order to raise the level of CO in the air to 1000ppm by volume STP, assuming the combustion reaction in the engine is C8H8. Using the ideal gas law, the number of moles of gasoline needed is calculated to be 1840.36 moles. This is then converted to ppm, which gives a result of 1.84ppm. Knowing that 1 mole of octane produces 8 moles of CO, the number of moles of C8H8 needed is determined to be 0.23. Multiplying this by the m

Homework Statement



Assume that an incorrectly adjusted lawn mower is operated in a garage such that the combustion reaction in the engion is C8H8. If the dimentions of the garage are 5x3x3 meters. How many grams of gasoline must be burned to raide the levl of CO in the air to 1000ppm by volume STP?

Homework Equations



PV=nRT

The Attempt at a Solution



101325 (45) = n(8.314)(298)
4559625 = n(2477.572)
n = 1840.36024moles

1840.36.../1000
1.84ppm

C8H8 + 6O2 ----> 8CO + 4H2O.

1 mole octane = 8 moles of CO

1.84/8 = 0.23 (moles of C8H8)

Mr C8H8 = 104.15 (have no idea why I took Mr of CO).

mass = n*Mr

mass = 0.23*104.15

mass = 23.98g gasoline needed

Is this correct? Cheers guys

1.84ppm? How is it related to the question?
 

Related to Grams of gasoline needed to raise level of CO in air.

1. How is the amount of gasoline needed to raise CO levels in the air calculated?

The amount of gasoline needed is calculated by using a conversion factor that relates the amount of CO produced by burning one gram of gasoline. This factor is typically expressed as grams of CO produced per gram of gasoline burned.

2. What is the average amount of gasoline needed to raise CO levels in the air?

The average amount of gasoline needed can vary depending on factors such as the type of gasoline, the efficiency of the burning process, and the volume of air being affected. However, on average, it takes about 1 gram of gasoline to produce 2.3 grams of CO.

3. Is the amount of gasoline needed to raise CO levels in the air the same for all types of vehicles?

No, the amount of gasoline needed can vary depending on the type and efficiency of the vehicle. For example, a newer and more efficient car may require less gasoline to produce the same amount of CO compared to an older, less efficient car.

4. How does the amount of gasoline needed to raise CO levels in the air affect the environment?

The amount of gasoline needed to raise CO levels in the air contributes to air pollution and can have negative effects on the environment and human health. Increased levels of CO can also contribute to the formation of smog and acid rain.

5. Can the amount of gasoline needed to raise CO levels in the air be reduced?

Yes, there are ways to reduce the amount of gasoline needed to raise CO levels in the air. These include using more efficient vehicles, reducing the number of vehicles on the road, and using alternative forms of transportation such as public transit or biking. Additionally, using cleaner sources of energy for transportation, such as electric or hybrid vehicles, can also help reduce the amount of CO produced from burning gasoline.
