Question

A major component of gasoline is octane . When octane is burned in air, it chemically reacts with oxygen gas to produce carbon dioxide and water .

What mass of carbon dioxide is produced by the reaction of of octane?

Round your answer to significant digits.

Please be detailed with your explanation.

A major component of gasoline is octane (C8H18) . When octane is burned in air, it chemically reacts with oxygen gas (O2) to produce carbon dioxide (CO2)and water (H2O). What mass of carbon dioxide is produced by the reaction of 7.32 gof octane?

Explanation / Answer

2 C8H18 + 25 O2 ---> 16 CO2 + 18 H2O

MOLES OF OCTANE IN 7.32 gm

= 7.32/(96+18) = 0.0642 moles

now 2 moles of octane produces 16 moles of CO2

so 0.0642 moles of octane will produce

=> 8*0.0642 = 0.5136 moles of co2

i.e. 0.5136*44 = 22.598gm of Co2
