if aluminum has an atomic number of 13 and an atomic mass of 26.98 and oxygen has an atomic number of 8 and an atomic mass of 16.00, then what is the mass of one mole of al2o3?

enter the answer rounded to two decimal points.

The mass of 1 mole of is 101.96 amu.

Explanation:

is a compound. One mole of a compound has a mass which is equal to the molecular weight (molar mass) of the compound expressed in 'amu' and it contains molecules of that compound.

To calculate the molar mass of the compound, we multiply the number of atoms of an element with its atomic mass. Molar mass of will be:

Atomic mass of Aluminium = 26.98 amu

Number of atoms of Aluminium = 2

Atomic mass of Oxygen = 16.00 amu

Number of atoms of Oxygen = 3

Molecular weight of = = 101.96 amu

Hence, the mass of 1 mole of is 101.96 amu.
