Which option gives the correct way to increase molarity if volume remains same?
Answer and explanation
Correct answer: Increase moles of solute
At constant solution volume, molarity changes directly with the amount of solute: M = n/V. Increasing n while keeping V unchanged therefore increases M. Changing the wording or colour has no effect on the number of solute moles. The solvent option is not a reliable direct method when the stated final volume is fixed.
