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
