Answer:
5.05 × 10²⁴ Zn Atoms
Explanation:
In order to find the number of atoms we will follow these two steps;
Step 1: Finding out the moles of Zn as;
Moles = Mass / A. Mass
Moles = 549 g / 65.38 g/mol
Moles = 8.397 moles
Step 2: Calculating No. of Atoms as:
According to Avogadro's Law, each mole contains 6.022 × 10²³ particles. These particles can be any entity i.e. atoms, molecules, formula units, ions e.t.c. So,
No. of Atoms = Moles × 6.022 × 10²³ atoms/mol
No. of Atoms = 8.397 mol × 6.022 × 10²³ atoms/mol
No. of Atoms = 5.05 × 10²⁴ Zn Atoms
