Molar Mass Of Aluminium
The Elemental Beauty of Aluminium
Before we explore the molar mass of aluminium, let’s appreciate its elemental properties. Aluminium, represented by the chemical symbol Al, is a silvery-white, non-ferrous metal. It is the third most abundant element in Earth’s crust, making up approximately 8.23% of the Earth’s mass. Despite its prevalence, extracting pure Al from its ores was once a complex and energy-intensive process.
Calculating the Molar Mass of Aluminium
The molar mass of Al is the mass of one mole of Al atoms. To calculate it, we consider the atomic mass of Al, which is approximately 26.98 atomic mass units (amu). One mole of any element contains Avogadro’s number of atoms, which is approximately 6.022 x 10^23 atoms.
Molar Mass of Aluminium = Atomic Mass of Aluminium x Avogadro’s Number
Molar Mass of Al ≈ 26.98 amu x 6.022 x 10^23 atoms/mol
Molar Mass of Al ≈ 26.98 grams per mole (g/mol)
Thus, the molar mass of aluminium is approximately 26.98 g/mol, which means that one mole of Al atoms has a mass of 26.98 grams.
