2.3 moles of helium gas is at a pressure of 1.70 atm and the temperature is 41 °C. What is the volume of the gas?

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.

A, it is falling action my have a good day
