Percentage composition of oxygen in al2O3 |
|
Answer» n:Given COMPOUND : ( Aluminum oxide )We've to find its percentage composition.Let's find the molecular MASS of ALUMINIUM oxide Firstly.→ Molecular mass of Aluminium oxide = 27 ( 2 ) + 16 ( 3 )→ Molecular mass of aluminium oxide = 54 + 48→ Molecular mass of aluminium oxide = 102 gNow, we have to find the percentage composition of oxygen in aluminium oxide.→ → 47.05 %Hence, percentage composition of oxygen in aluminium oxide is 47.05% |
