What mass of LiOH would need to be dissolved in 500.0 mL of water to produce a solution with a pH of 12.40

Hope you find the answer

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.

Ireally don’t know bruh

Oxygen= 88ghydrogen= 12g
