Question

Benzene (C6H6) is vaporized in an automobile engine and combusts to produce carbon dioxide gas and water vapor. What is the mass (in grams) of carbon dioxide (CO2) produced at 250°C and 101.3 kPa?

Answer 1

The mass of carbon dioxide produced from the combustion of benzene in an automobile engine is 468.66 grams.

Step-by-step explanation:

The balanced equation for the combustion of benzene (C6H6) is:

C6H6 + 15O2 → 6CO2 + 3H2O

To find the mass of CO2 produced, you need to know the molar mass of benzene. The molar mass of benzene is 78.11 g/mol. Use the molar ratio from the balanced equation to calculate the mass of CO2 produced:

1 mol of C6H6 produces 6 mol of CO2

78.11 g of C6H6 produces x g of CO2

Solve for x:

x = (78.11 g CO2) / (78.11 g/mol) * (6 mol CO2 / 1 mol C6H6)

x = 468.66 g CO2

Therefore, the mass of carbon dioxide produced is 468.66 grams.
