Answer and explanation
Correct answer: 2 percent
Mass by volume percent means grams of solute present in 100 mL of solution. The solution contains 2 g KCl in exactly 100 mL, so its concentration is 2 g per 100 mL, or 2% (m/V). Option B is correct. This is not mass percent, because the denominator is volume, not total mass.
