Answer 2

Determining the Mass Fraction of AL2O3

To determine the mass fraction of AL2O3, we can use the formula:

Mass Fraction = (Mass of AL2O3 / Total Mass of the Compound) * 100%

Let's calculate the mass fraction of AL2O3 using the given information.

The molar mass of AL2O3 is 102 g/mol.

Using the formula from source we can calculate the mass fraction of AL2O3: m (Al2O3) = 102 / 102 = 1

Therefore, the mass fraction of AL2O3 is 1%.

This calculation is based on the molar mass of AL2O3 and the given formula for determining the mass fraction.
