a. 0.1M C2H5OH

Explanation:

This could be considered using the idea of colligative property of solutions.

Colligative properties are those properties of solutions that depend on the ratio of the number of solute particles to the number of solvent molecules in a solution, and not on the nature of the chemical species present. The number ratio can be related to the various units for concentration of solutions.
