The molar mass of silver is 107.9 g/mol. To find the mass of a single silver atom, we need to use Avogadro’s number, which is 6.022 x 10²³ atoms/mol. This number represents the number of atoms in one mole of any substance.
To calculate the mass of a single silver atom, we divide the molar mass of silver by Avogadro’s number:
Mass of a single silver atom = Molar mass of silver / Avogadro’s number
Mass of a single silver atom = 107.9 g/mol / 6.022 x 10²³ atoms/mol
Mass of a single silver atom ≈ 1.79 x 10⁻²² g
So, the mass of a single silver atom is approximately 1.79 x 10⁻²² grams.
