Verified step by step guidance

Understand that solubility is a measure of how much solute can dissolve in a given amount of solvent under specific conditions.

Recognize that solubility is commonly expressed as the amount of solute dissolved per a certain volume of solvent, often water, because volume is easier to measure than mass of solvent in many practical situations.

Note that the expression 'grams of solute dissolved per 100 mL of water' directly relates the mass of solute to a fixed volume of solvent, which is a standard way to report solubility in aqueous solutions.

Compare the other options: 'grams of solvent per 100 grams of solute' reverses the typical ratio and is not standard; 'moles of solute dissolved per mole of solvent' is a mole ratio but less commonly used for solubility; 'moles of solute per liter of solution at standard temperature and pressure' describes molarity but includes the total solution volume, not just solvent volume, and STP is more relevant for gases.

Conclude that the expression 'grams of solute dissolved per 100 mL of water' is the generally accepted way to represent solubility of a compound in water.
