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
