Regular gasoline (C8H18) reacts with oxygen gas to form carbon dioxide gas and water vapor.

If your tanks of gasoline holds about 10.5 kg of gasoline, how many liters of carbon dioxide are formed at 24 degrees Celcius and 725mm Hg from the combustion of one tank of gasoline?

To calculate the liters of carbon dioxide formed from the combustion of one tank of gasoline, we need to use the information provided and apply stoichiometry.

First, let's write the balanced chemical equation for the combustion of gasoline:
C8H18 + 12.5O2 -> 8CO2 + 9H2O

From the equation, we can see that for every mole of gasoline (C8H18), 8 moles of carbon dioxide (CO2) are formed.

Step 1: Convert the mass of gasoline to moles
We are given that the gasoline tank holds about 10.5 kg of gasoline. To convert this mass to moles, we need to use the molar mass of gasoline.
The molar mass of gasoline (C8H18) can be calculated as follows:
(12.01 g/mol x 8) + (1.01 g/mol x 18) = 114.23 g/mol

Now, we can convert the mass of gasoline to moles:
10.5 kg gasoline x (1000 g/1 kg) x (1 mol/114.23 g) = 91.84 mol gasoline

Step 2: Use stoichiometry to determine moles of CO2
From the balanced equation, we know that 1 mole of gasoline produces 8 moles of CO2.
Therefore, the moles of CO2 produced can be calculated as:
91.84 mol gasoline x (8 mol CO2 / 1 mol gasoline) = 734.72 mol CO2

Step 3: Convert moles of CO2 to liters at the given conditions
To convert moles of CO2 to liters, we need to use the ideal gas law equation:
PV = nRT

Given:
Temperature (T) = 24 degrees Celsius = 24 + 273 = 297 Kelvin
Pressure (P) = 725 mmHg

We need to convert pressure to atm, as that is the standard unit for the ideal gas law equation:
725 mmHg x (1 atm/760 mmHg) = 0.954 atm

R is the ideal gas constant, which is 0.0821 L·atm/(mol·K).

Now, we can calculate the volume of CO2 produced:
V = (nRT) / P
V = (734.72 mol CO2 x 0.0821 L·atm/(mol·K) x 297 K) / 0.954 atm
V ≈ 18394.84 L

Therefore, approximately 18394.84 liters of carbon dioxide are formed from the combustion of one tank of gasoline at 24 degrees Celsius and 725 mmHg.
