Isaac physics - essential pre-uni chemistry F3.4 question help pls!!!!!!!!!!!!!!!!!!

what is the enthalpy of solution for HCl (g) in this equation:

TiCl4 (l) + 2H2O (l) -> TiO2 (s) + 4HCl (aq)

enthalpy change for the overall reaction is: -232.3
enthalpy of formation of TiCl4 (l) is: -804.2
enthalpy of formationTiO2 (s) is: -939.7

enthalpy of 4HCl (aq) is unknown
and enthalpy of 2H2O (l) is unknown

(Part J)

What are you thinking so far?

i'm not sure because there's two enthalpy values that are missing from both sides? ( 2H2O(l) and 4HCl(aq) ). how would you work these out?

if its on isacphysics the enthalpy of formation of h2o is the same as the combustion of h2 on the table provided but i dont know how to work it out still

yeah, i'm pretty sure the table is incorrect/missing some info
