Consider these reactions, where M represents a generic metal. 

1. 2 M(s) + 6 HCl(aq) → 2 MCl3(aq) + 3 H2(g)             ΔH1 = -623.0 kJ

2. HCl(g) → HCl(aq)                                                 ΔH2 = -74.8 kJ

3. H2(g) + Cl2(g) → 2 HCl(g)                                     ΔH3 = -1845.0 kJ 

4. MCl3(s) → MCl3(aq)                                             ΔH4 = -309.0 kJ

Use the information above to determine the enthalpy of the following reaction

2M(s) + 3Cl2(g) → 2MCl3(s)                                    ΔH =      kJ
