The molecular structure of the solids has lower ability to conduct electricity due to tight holding by nucleus.
<h3>Why molecular solids are poor conductors?</h3>
Molecular solids are also poor conductors of electricity because their valence electrons are tightly held by the nuclear charges present in the nucleus while on the other hand, Metals are good electrical conductors in the solid form due to the presence of free electrons that helps in the conduction of electricity.

Because water vapor, uncontained, will diffuse out into the atmosphere and is not close enough to condense back into the liquid water, so no equilib. can be established.
A.)49.4974874 moles or 49.5 moles
B.)2.980808730172671e+25 or 3e+25
Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of gases.
I believe the answer is 1-Water :)
