Which expression describes solubility as grams of solute soluble in 1 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: (A)

Solubility is about how much solute can dissolve in a given amount of solvent, described as grams per unit volume of solvent. When the statement uses grams of solute soluble in 1 mL of solvent, it’s giving grams per milliliter, which is exactly the form for solubility in this case. The other expressions shift the reference (for example, grams per 100 mL) or describe how much solvent is needed to dissolve a certain amount of solute, which is the inverse relationship and not the stated grams-per-volume form. So this expression best matches how solubility is defined in this context.
