Answer:
In 4.56 moles of LiCl 27.46*10^23 formula units is present.
Explanation:
Formula units is defined as the empirical formula for any ionic, covalent and network solid compounds which are used as a single unit for stoichiometric calculations. Also It can be defined as the lowest whole number ratio of ions which can be represented in an ionic compound.
We are given
4.65 moles of Lithium chloride.
One mole of Lithium chloride has 6.022*10^23 unit Formula unit
In 4.56 moles of Lithium Chloride the formula unit will be
= 4.56*6.022*10^23
Formula units = 27.46 * 10^23
It is clear that in 4.56 moles of Lithium Chloride will contain 27.46*10^23 Formula unit.
Therefore in 4.56 moles of LiCl 27.46*10^23 formula units is present.
