Zinc picolinate, Zn(C6H4NO2)2\text{Zn}(\text{C}_6\text{H}_4\text{NO}_2)_2Zn(C6H4NO2)2, is a dietary supplement used to prevent or treat zinc deficiency.
A typical single-tablet dose of this supplement contains 22.0 mg22.0\text{ mg}22.0 mg of zinc.
Calculate the mass, in g\text{g}g, of zinc picolinate in a typical single-tablet dose. Give your answer to three significant figures.
