The number of atoms of silver in 307 grams of silver is 1.71 × 10²⁴ atoms
Avogadro's number:
Avogadro's number, number of units in one mole of any substance equals to 6.02214076 × 10²³
Therefore,
1 mole(107.8682 grams) of silver(Ag) = 6.022 × 10²³ atoms
307 grams of Ag = ?
cross multiply
number of atoms of silver = 6.022 × 10²³ × 307 / 107.8682
number of atoms of silver = 1848.754 × 10²³ / 107.8682
number of atoms of silver = 17.1390085308 × 10²³
number of atoms of silver = 1.71 × 10²⁴
