Final answer:
The solubility of sodium chloride in water is 36.0 g per 100 g water at 20°C. Solubility is often measured as the grams of solute per 100 g of solvent. The temperature must be specified because solubility varies with temperature.
Step-by-step explanation:
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 20°C. The temperature must be specified because solubility varies with temperature.
