Answer:
3.0 x 10⁻⁴ moles
Explanation:
Given parameters:
Amount of Ag atoms = 1.8 x 10²⁰ atoms
Unknown:
Number of moles of Ag atoms
Solution:
From mole concept, we know that a mole of a substance contains Avogadros number of particles.
The Avogadro's number of particles is 6.02 x 10²³.
Now:
Number of moles
= number of particles/6.02 x 10²³
Therefore:
Number of moles= 1.8 x 10²⁰ / 6.02 x 10²³
Number of moles = 0.3 x 10⁻³ moles
= 3.0 x 10⁻⁴ moles
