If your car gets 21.4 mpg, how many L of CO2, will you release into the atmosphere, if you drove the 1280miles from Towson University to key West Florida for a much needed break after taking Chemistry 121? Assume 1.05atm and 17.0C.
What would your carbon load be in lbs (lbs of CO2 released) per mile traveled?
Assume that gasoline is octane; therefore the following reaction should be considered.
____C8H18(I) +_____O2(g)„³____CO2(g)+__H2O(g)
Physical Constants that you will find necessary:
Density of octane =0.7025g/ml
1Gal=3.79L
1LB=454g
The balanced equation minus the phases to save typing space.
2C8H18 + 25O2 ==> 16CO2+ 18H2O
21.4 mpg x #gallons = 1280 miles
Solve for gallons needed.
.
Convert gallons octane to L octane.
Using density convert L octane to grams octane.
Convert g octane to mols octane. mol = g/molar mass.
Using the coefficients in the balanced equation, convert mols octane to mols CO2 and using PV = nRT and the conditions listed convert mols CO2 to L.
This should get you started. Post your work if you need further assistance.
How to solve for gallons needed?
Can you please do the all things for me please, I really need help. Thank you so much.
21.4*x = 1280.
Solve for x.
No. We don't do homework for you. We HELP you do your homework. You aren't asking for help; you're asking me to do your homework for you. We are tying to help so you will learn how to do these things yourself. If you need help you've come to the right place. If you need someone to do your work for you this is not the place.
gallons octane to L octane will be
#gallons x 3.785 liters right?
The gallons I got 59.81
and the L octane 59.81*3.785= 226.38
226.38 x 1000 = 226380mL
226380mL x 0.7025 g/mL = 159031.95grams.
I found those result is correct?
the answer is 9.2 L and 34 lbs.
To find out how many liters of CO2 your car will release into the atmosphere for a 1280 miles trip, we need to use the given information about your car's fuel efficiency.
1. Convert miles to liters of fuel:
Since your car gets 21.4 mpg (miles per gallon), we can calculate the amount of fuel used for the trip by dividing the distance traveled by the fuel efficiency:
Fuel used (in gallons) = 1280 miles / 21.4 mpg
2. Convert gallons of fuel to liters:
Knowing that 1 gallon is equal to 3.79 liters, we can convert the fuel used from gallons to liters by multiplying it by the conversion factor:
Fuel used (in liters) = Fuel used (in gallons) * 3.79 liters/gallon
3. Calculate the amount of CO2 released:
We need to consider that the reaction provided represents the combustion of octane, and we can use stoichiometry to calculate the amount of CO2 produced. From the balanced equation, we can see that 1 mole of C8H18 produces 8 moles of CO2.
To calculate the moles of octane used, we first need to find the mass:
Mass of octane used = Fuel used (in liters) * Density of octane * 1000 (to convert g/ml to g/L)
Next, we can calculate the moles of octane:
Moles of octane used = Mass of octane used / molar mass of octane
Finally, we can determine the amount of CO2 produced:
Moles of CO2 produced = Moles of octane used * 8
4. Convert moles of CO2 to grams and then to pounds:
Using the molar mass of CO2 (44.01 g/mol), we can calculate the mass of CO2 produced:
Mass of CO2 produced (in grams) = Moles of CO2 produced * molar mass of CO2
To convert the mass of CO2 to pounds, we can use the conversion factor 1 pound = 454 grams:
Mass of CO2 produced (in pounds) = Mass of CO2 produced (in grams) / 454
Now we have the answer to the first part of the question, the liters of CO2 released into the atmosphere.
To find the carbon load in lbs per mile traveled, we need to divide the mass of CO2 produced by the distance traveled:
Carbon load (in lbs per mile) = Mass of CO2 produced (in pounds) / 1280 miles
By following these steps, you can calculate the liters of CO2 released and the carbon load in pounds per mile traveled for your trip from Towson University to Key West Florida.
