Mass Number Of Aluminium



1 mole of Aluminium Oxide (Al2O3) = 2 × 27 + 3 × 16 = 102 g
We know, 102 g of Aluminium Oxide (Al2O3) = 6.022 × 1023 molecules of Aluminium Oxide (Al2O3)

The gram atomic mass of aluminum, which is defined as the mass of Avogadro's Number of atoms of the element, is 26.9815. To the justified number of significant digits, this is the same as the gram. Atomic Mass of Aluminium Atomic mass of Aluminium is 26.9815 u.

We know, The number of atoms present in given mass = (Given mass ÷ molar mass) × Avogadro number
MassMass Number Of Aluminium
= (0.051 ÷102 ) × 6.022 × 1023 molecules of Aluminium Oxide (Al2O3)
= 3.011 × 1020 molecules of Aluminium Oxide (Al2O3)

Mass Number Of Aluminium


The number of Aluminium ions (Al3+) present in one molecule of aluminium oxide is 2.
Therefore, the number of Aluminium ions (Al3+) present in 3.011 × 1020 molecules (0.051 g ) of Aluminium Oxide (Al2O3)
Aluminum 5052 h32 properties

= 6.022 × 1020
