How many atoms would be contained in 549 grams of zinc

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
