What final volume of solution is needed if 30.15g Nh2Cs3 is dissolved in enough water to make a solution with a molar concentration of 2.5M? the atomic mass of NhCs:
Nh= 20.15
Cs= 19.94

i need a final volume of L
​

Sorry i dont understand the question can you rephase it?

Of course: ) what’s your name ?

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.
