formulae for aluminium oxide =Al₂O₃
mass of aluminium in its one mole of oxide = 54gm
now totla no. of moles = [tex] \frac{given mass}{molecular mass } [/tex] =
= 2 mole
so mass of aluminium in 2 mole = 54 ˣ 2 = 108 gm
mass of aluminium in its one mole of oxide = 54gm
now totla no. of moles = [tex] \frac{given mass}{molecular mass } [/tex] =
so mass of aluminium in 2 mole = 54 ˣ 2 = 108 gm
