Answer and explanation
Correct answer: 4 percent
Mass percentage is mass of solute divided by total mass of solution, multiplied by 100. Here, mass percent = 10/250 × 100 = 4%. Therefore, option B is correct. Because the total solution mass is already given as 250 g, it should be used directly; adding another mass would double-count material.
