Answer:
1.93 x 10²⁶ formula units
Explanation:
Given parameters:
Number of moles of LiCl = 3.2 x 10² moles = 320moles
Unknown:
Number of formula units in this compound = ?
Solution:
The mole is used a reference to determine the number of substances matters contain.
A mole contains the Avogadro's number of particles.
So;
1 mole of a substance contains 6.02 x 10²³ formula units;
320 moles of LiCl will contain 320 x 6.02 x 10²³ = 1.93 x 10²⁶ formula units
