Here is the combustion reaction for octane (c8h18), which is a primary component of gasoline. how many moles of co2 are emitted into the atmosphere when 20.6 g of c8h18 is burned?

0.5421 moles of carbon dioxide are emitted into the atmosphere.

Explanation:

Moles of octane =

According to reaction 1 mol of octane gives 3 moles of carbon dioxide.

Then, 0.1807 moles of octane will give:

of carbon dioxide

0.5421 moles of carbon dioxide are emitted into the atmosphere.
