Which expression describes solubility as grams of solute soluble in 100 mL of solvent?

Which expression describes solubility as grams of solute soluble in 100 mL of solvent?

• A. g of solute soluble in 1 mL of solvent
• B. g of solute soluble in 100 mL of solvent
• C. mL of solvent required to dissolve 1 g of solute
• D. mL of solvent required to dissolve 100 g of solute

Answer: (B)

Solubility is the amount of solute that will dissolve in a fixed amount of solvent at a given temperature. The standard way to express this is by stating how many grams of solute can dissolve in a specific volume of solvent, typically 100 mL. That makes the expression "grams of solute soluble in 100 mL of solvent" the correct way to describe solubility. The other options describe either the amount of solvent needed to dissolve a certain amount of solute (which is not how solubility is defined) or use nonstandard units (like per 1 mL) that don’t match the given phrasing.
