Answer:
800× 10²³ atoms
Explanation:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
In a similar way,
27 amu of Al = 1 mole = 6.022 × 10²³ atoms of Al
For 3588.3 amu,
3588.3 / 27 = 132.9 mol
132.9 mol × 6.022 × 10²³ atoms / 1 mol
800× 10²³ atoms
