The number of atoms present in 0.58 mole of magnesium, Mg is 3.49×10²³ atoms.
An atom is the basic building block of chemistry. It is the smallest unit into which matter can be divided without the release of electrically charged particles.
Avogadro's hypothesis
1 mole of Mg = 6.02×10²³ atoms
Therefore,
0.58 mole of Mg = 0.58 × 6.02×10²³
0.58 mole of Mg = 3.49×10²³ atoms
Thus, 3.49×10²³ atoms are present in 0.58 mole of Mg
