In which situation is mass-volume percentage directly most useful?
Answer and explanation
Correct answer: When solute is given in grams and solution in millilitres
Mass-volume percentage is defined as grams of solute present in 100 mL of solution. Therefore, data stated as solute mass in grams and solution volume in millilitres can be used directly. Moles would suggest mole fraction or molarity, kilograms of solvent suggest molality, and temperature alone cannot determine a concentration.
