A solution has 10 percent solute by mass. What is the mass percent of solvent in the same solution?
Answer and explanation
Correct answer: 90%
For a binary solution containing only solute and solvent, their mass percentages add to 100%. Therefore solvent percentage = 100 − 10 = 90%. Option C is correct. The value 100% would describe the whole solution, not just the solvent, while 50% has no basis in the given information.
