If a question gives grams of solute and millilitres of solution, which concentration term is most direct?
Answer and explanation
Correct answer: Mass-volume percentage
Mass-volume percentage is defined as grams of solute per 100 mL of solution, so grams and millilitres match its definition directly. Molarity would require converting mass to moles and millilitres to litres. Molality requires solvent mass in kilograms, while mole fraction requires moles of every component. Therefore C is the most direct term.
