Enthalpy?

[Chubypig]

I'm working on a chemistry lab, and I'm trying to find the enthalpy in kJ/mol of NH4Cl (aq) I've searched google, and my text book to no avail. as a last hope, could any of you help me?

please?

From what I remember from chemistry classes, the enthalpy of a system cannot be measured and thus what you are asking makes no sense. Only the change in enthalpy can be measured.
If I remember correctly, the standard enthalpy change of a substance is the resulting change in enthalpy that from the formation of the substance from its constituents.
A quick google revealed the standard enthalpy change of NH4Cl (s) to be -314.55 kJ/mol.
