Answer:
Solubility.
Explanation:
Solubility may be defined as the amount of solute dissolved in a fixed amount of the solvent at a particular temperature and pressure. The solubility of a substance can be changed by increase or decreasing the physical properties like temperature and pressure.
The amount of substance is dissolved in 1dm3 of water at the fixed temperature of 25°C. Hence, it represents the solubility.
Thus, the correct answer is option (D).
