Type the correct answer in the box. Calculate the molar mass of aluminum oxide (Al2O3). Express your answer to four significant

Zepler [3.9K]

Molar mass can be given as the mass of each constitutive element in the formula unit. The molar mass of aluminum oxide is 101.957 grams.

<h3>What is a formula unit?</h3>

Formula unit can be defined as the one unit of the molecular formula of the compound. It describes the number of atoms of each element present in the compound.

The formula unit for Aluminum oxide is $\rm Al_2O_3$ . The molar mass has been the sum of the mass of aluminum and oxygen.

The molar mass of aluminum oxide has been given as:

$\rm Molar\;mass=2\;\times\;Al+3\;\times\;O\\Molar\;mass=2\;\times\;26.98\;+\;3\;\times\;15.99\;grams\\Molar\;mass=101.957\;grams$

The molar mass of aluminum oxide is 101.957 grams.
