###### Problem Details

Consider these reactions, where M represents a generic metal

2M(s) + 6HCl(aq) → 2MCl3(aq) + 3H2(g)              H = -748.0 kJ

HCl(g) → HCl(aq)                                                   H = -74.8

H2(g) + Cl2(g) → 2HCl(g)                                       H = -1845

MCl3(s) → MCl3(aq)                                               H = -317.0

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

2M(s) + 3Cl2(g) → 2MCl3(s)
