The correct answer is option A.
All the particles carry the same charge, which could be either positive or negative.
All the particles of substance X will have same charge on its surface, which is balanced by the oppositely charged ions in the water.
For example, soap solution (sodium palmitate) dissociates into ions:
C₁₅H₁₁COONa --> C₁₅H₁₁COO⁻ + Na⁺
The cations (Na⁺) passes into the water while the anions (C₁₅H₁₁COO⁻) form aggregates or colloids.

Answer:
0.850 g / cm3
Explanation:
The problem can be solved using the formula:
Density = mass / volume
Since two of the data are already provided in the problem, just plug in the values to the formula.
(Rearrangement of the formula from its standard form is not necessary at all)
