Answer:
69.37×10²³ atoms of silver
Explanation:
Given data:
Mass of sample = 1243 g
Number of atoms of silver = ?
Solution:
Number of moles of silver:
Number of moles = mass/molar mass
Number of moles = 1243 g/ 107.87 g/mol
Number of moles = 11.52 mol
Number of atoms:
According to Avogadro Law,
1 mole contain 6.022×10²³ atoms
11.52 mol × 6.022×10²³ atoms / 1mol
69.37×10²³ atoms
