What mass of co2 is produced from the combustion of 2.00 gallons of gas? assume the gas is all octane (c8h18) with a density of 0.703 g/ml. 1 gallon = 3785 ml

Answer : The mass of produced form the combustion is, 16.43 kg

Explanation :

Density : It is defined as the mass contained per unit volume.

Formula used for density :

First we have to calculate the mass of octane.

Given :

Density of octane = 0.703 g/mL

Volume = 2.00 gallons = 7570 mL

conversion used : 1 gallon = 3785 mL

Now put all the given values in the above formula, we get:

Now we have to calculate the moles of octane.

Molar mass of octane = 114 g/mole

Now we have to calculate the moles of .

The balanced chemical combustion reaction of octane will be:

From the balanced chemical reaction we conclude that:

As, 2 moles of react to give 16 moles of

So, 46.68 moles of react to give moles of

Now we have to calculate the mass of .

Molar mass of = 44 g/mol

Thus, the mass of produced form the combustion is, 16.43 kg
