Which solution contains the greatest number of solute 2L of 0.5 M 2L of 2M 0.5L of 2M 0.5L of 0.5M

The correct answer is:   bri hope this answer was ! : )

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.
