Melanie? has a spectacular aura about
Enthalpy changes Chemistry?

I have no idea how to do this...

Determine the enthalpy change for the reaction:
Li2O(s) + 2HCl(g) ® 2LiCl(s) + H2O(l)
The following information may prove helpful:
DH°f(Li2O) = -598.73 kJ/mol
DH°f(HCl) = -92.31 kJ/mol
DH°f(LiCl) = -408.27 kJ/mol
DH°f(H2O) = -285.83 kJ/mol
