What is the mass percentage of solute in a solution made from 10 g solute and 90 g solvent?
Answer and explanation
Correct answer: 10 percent
Mass percentage is calculated using the mass of solute divided by the total mass of solution, multiplied by 100. The total mass is 10 g + 90 g = 100 g. Therefore, mass percentage = (10/100) × 100 = 10%, so option A is correct. The 90% value represents the solvent percentage, not the solute percentage.
