How to obtain a concentration of 1 mM/dl of ammonia from ammonium chloride?

04 December 2023 1 3K Report

How many mg or g of ammonium chloride (NH4Cl) to obtain a final concentration of 1 mM/dl of ammonia (NH3) ?

My intuition is 1 mg FW / L, assuming that NH3 in solution is hydrated; however, the equilibrium chemical speciation varies with pH
