A scientist measures the standard enthalpy change for the

A scientist measures the standard enthalpy change for the following reaction to be -173.9 kJ: HCl(g) + NH3(g) ⇒ NH4Cl(s) Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of NH3(g) is kJ/mol.
