Answer:
Precisely zero. aluminum oxide is not an ion. It is a neutral compound made of ions of aluminium combined with oxygen ions.
Also if u need tlga here it is:
you could simply divide 256g by the molar mass of AI2O3 (101.96 g/mol) to find the amount of moles. This would be 256/101.96 moles.
Consequently the amount of molecules of Al2O3 would be 256/101.96* N_a (This is Avogadro’s constant, not sodium).
≈ 1.51 * 10^24
(but its better tlga 0 yung sagot mo)
