The question asks to calculate the reaction enthalpy for the synthesis of hydrogen bromide gas. Shouldn't the unit of the answer be kJ/mol instead of just kJ?

reaction enthalpies may not just be indicating 1 mol of substance so it's only kJ. If it were enthalpy of formation or enthalpy of combustion, then it would be kJ/mol as it's the reaction enthalpy of the formation/combustion of 1 mole of a substance
