Answer:

7.87 x 10²³ atoms

Explanation:

The number of LiCl units is related to moles using Avogadro's constant (6.022 × 10²³ mol⁻¹):

(0.654 mol)(6.022 × 10²³ mol⁻¹) = 3.93 x 10²³ LiCl

One LiCl unit is composed of two atoms, one Li atom and one Cl atom, so the amount is multiplied by 2:

(3.93 x 10²³)(2) = 7.87 x 10²³ atoms
