Answer:
32.7 kilograms of aluminium oxide will be produced.
Explanation:

Mass of aluminum = 17.3 kg = 17300 g (1 kg = 1000 g )
Moles of aluminium = 
According to reaction, 2 moles of aluminum gives 1 mole of aluminum oxide,then 640.74 moles of aluminum will give:
of aluminum oxide
Mass of 320.37 moles of aluminum oxides:
320.37 mol × 102 g/mol = 32,677.74 g = 32.67774 kg ≈ 32.7 kg
32.7 kilograms of aluminium oxide will be produced.
i believe the answer is success of a policy. if this was correct please mark brainliest and lmk if you have any more questions x
D.) There must be an equal number of atoms of each element on both sides of the equation
