Question

Calculate the percentage composition of aluminium oxide (Al2O3) (Al=27, O=16)​

Answer 1

Solution,

Molecular mass of Al2O3= 2*27+3*16

=54+48

Now,

Percent of Al = (Mass od Al in Al2O3) / (molecular mass of Al2O3)

=(54/102) × 100%

=52.94%

the percentage of Al in Al2O3 is 52.94%

Answer 2

Answer:

The percentage of Al in Al2O3 is 52.94%.

Explanation:

Aluminum oxide exists as a chemical compound of aluminum and oxygen with the chemical formula Al 2O 3. It exists the most typically occurring of several aluminum oxides and is particularly identified as aluminum (III) oxide.

Alumina, commonly understood as aluminum oxide (Al2O3), exists as an inert, odorless, white amorphous material often utilized in industrial ceramics. Due to its outstanding properties, alumina includes contributed to a substantial number of life-extending and society-enhancing applications. It exists widely used in the medical field and modern warfare.

The molecular mass of Al2O3= 2*27+3*16

=54+48

Now,

Percent of Al = (Mass of Al in Al2O3) / (molecular mass of Al2O3)

=(54/102) × 100%

=52.94%

The percentage of Al in Al2O3 is 52.94%.
