Answer: 1082 g of carbon dioxide are produced for every 350 grams of octane reacted in the engine
Explanation:
To calculate the moles :
According to stoichiometry :
As 2 moles of octane give = 16 moles of
Thus 3.07 moles of octane will give = of
Mass of
Thus 1082 g of carbon dioxide are produced for every 350 grams of octane reacted in the engine
The amount of atoms of Phosphorus in 3.80 mol of copper (II) phosphate would be equivalent with :
3.80 mol x (6.022 x 10^23 molecules)/ (1 mol)
Hope this helps
