Concentration refers to what aspect of a solution?

• A. The total mass of the solution
• B. The volume of solvent only
• C. The amount of solute in a solution
• D. The temperature.

Answer: (C)

Concentration is about how much solute is present in a solution. It’s a ratio that describes how much dissolved substance exists relative to the amount of solution (or solvent). That’s why the option “the amount of solute in a solution” best captures what concentration measures. The total mass of the solution isn’t the defining factor, because two solutions can have the same total mass but different amounts of solute and solvent, resulting in different concentrations. The volume of solvent alone ignores the solute, so it doesn’t fully describe concentration. Temperature isn’t the measure of concentration itself, though it can affect volume and solubility, which can change concentration readings.
