Quick question! !

how many atoms are in 0.654 moles of lithium chloride?

3.93 x 1023 atoms

7.87 x 1023 atoms

9.20 x 1023 atoms

1.18 x 1024 atoms

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

9

fx=4=4⋅5=20(2+7)−2⋅3=3·2+7=9
