Answer:
Water has polar O-H bonds. The negative O atoms attract the positive H atoms in nearby molecules, leading to the unusually strong type of dipole-dipole force called a hydrogen bond.
Explanation:
Density = mass / volume so density = 62.5429 / 3.24 = 19.3 g/ml. This is the density of gold.
Because of gravity not pulling you down

The mass percentage of water (H₂O) in cadmium chloride tetra hydratesolution is equal to the 28.2%.
<h3>How do we calculate mass percentage?</h3>
Mass percentage of any substabce present in any solution will be calculated as:
Mass percent = (Mass of substance/Total mass of solution)×100%
According to the question,
Mass of water (H₂O) = 18.02 g/mol
Mass of solvent (CdCl₂.4H₂O) = 183.32 + 4(18.02) = 255.4 g/mol
On putting values, we get
Mass percent = (18.02 / 255.4) × 100% = 28.2%
Hence mass percent of water is 28.2%.
