2.1 x 10²²atoms
Explanation:
Given parameters:
Mass of silver = 3.78g
Unknown:
Number of atoms of silver = ?
Solution:
To solve this problem, we first find the number of moles of the silver from the given mass.
Number of moles =
Molar mass of Ag = 108g/mole
Number of moles = = 0.035mole
Now;
A mole of any substance contains 6.02 x 10²³ atoms
0.035 moles of Ag will contain 0.035 x 6.02 x 10²³ = 2.1 x 10²²atoms
