lab report on Hess' law

I am currently doing a lab report on Hess' law and have the following question as part of the lab report to answer

 

5. Use the thermodynamic quantities given below to calculate the theoretical ΔH for this reaction: 

   NH3 + HCl → NH4Cl

  • ΔH°f for NH3 (aq) = - 80.29 kJ/mol
  • ΔH°f for HCl (aq) = - 167.2 kJ/mol
  • ΔH°f for NH4+ (aq) = - 132.5 kJ/mol
  • ΔH°f for Cl- (aq) = - 167.2 kJ/mol

 

Could someone point me in the direction of how to work this out? This may help me figure out if I've calculated the results from my experiment correctly
