Q: Answer the following question given this paragraph: The solubility of a substance is the amount of that substance that is required to form a saturated solution in a given amount of solvent at a specified temperature. Solubility is often measured as the grams of solute per 100 g of solvent. The solubility of sodium chloride in water is 36.0 g per 100 g water at 20C. The temperature must be specified because solubility varies with temperature. For gases, the pressure must also be specified. Solubility is specific for a particular solvent. We will consider solubility of material in water as solvent. Q: What term means the amount of a substance required to form a saturated solution in a given amount of solvent at a specified temperature? A: | OPTIONS:
- viscosity
- concentration
- turbidity
- solubility
A: solubility
