Answer:
<h2>1.505 × 10²⁴ particles</h2>
Explanation:
The number of particles in iron (II) chloride can be found by using the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 2.5 × 6.02 × 10²³
We have the final answer as
<h3>1.505 × 10²⁴ particles</h3>
Hope this helps you

Answer:
diiodomethane
Explanation:
The densities of each of the liquids mentioned in the question are stated below;
CCl4- 1.59 g/cm^3
Hexane- 0.672 g/cm^3
Benzene- 0.8765 g/cm^3
Diiodomethane- 3.3 g/cm^3
Clearly, the density of diiodomethane methane is almost the same as that of the desired granular material, hence the undesired granular material having a density of 2.04 g/cm3 will float in diiodomethane thus separating the two granular materials.
