Calculating the molar mass of a substance is very simple. To do this, you need to know the molar mass of each chemical element that is part of the substance. It is easy to recognize from the periodic table of chemical elements.
For the molar mass of Al2O3, the molar masses of aluminum and oxygen are needed (M is the molar mass).
M (Al) = 27g / mol, M (O) = 16g / mol.
Each molar mass of an element must be multiplied by its coefficient.
M (Al2O3) = 27 * 2 + 16 * 3 = 102
Answer: 102g / mol.
