2.4 × 10^24
Correct Answer: option C: Formation of sea ice
Reason:
<span> In cold regions, changes in salinity alters the water present in ocean. Further, water density also changes with temperature. In general, water density in ocean water increases with decreasing temperature. This is because, when salt is ejected into the ocean as sea ice forms, the water's salinity increases. Since, salt water is heavier, the density of the water increases.</span>
Answer:
The solution has a higher osmotic pressure and higher boiling point than LiCl solution.
Explanation:
As concentrations of two aqueous solutions are same therefore we can write:
, and
where , and are lowering of vapor pressure, elevation in boiling point and osmotic pressure of solution respectively. is van't hoff factor.
= total number of ions generated from dissolution of one molecule of a substance (for strong electrolyte).
Here both and LiCl are strong electrolytes.
So, and
Hence, lowering of vapor pressure, elevation in boiling point and osmotic pressure will be higher for solution.
Therefore the solution has a higher osmotic pressure and higher boiling point than LiCl solution.
