Answer:

3.01 × 10²³ atoms

Explanation:

Given data:

Mass of sample of silver = 53.93 g

Number of atoms of silver = ?

Solution:

Number of moles of silver:

Number of moles = mass/ molar mass

Number of moles = 53.93 g/ 107.86 g/mol

Number of moles = 0.5 mol

Number of atoms of silver:

1 mole = 6.022 × 10²³ atoms

0.5 mol × 6.022 × 10²³ atoms /1 mol

3.01 × 10²³ atoms
