Copper(II) glycinate, Cu(C2H4NO2)2\text{Cu}(\text{C}_2\text{H}_4\text{NO}_2)_2Cu(C2H4NO2)2, is a neutral transition metal complex used as a dietary supplement.
A typical tablet of this supplement contains 2.50 mg2.50\text{ mg}2.50 mg of copper.
Calculate the mass, in g\text{g}g, of copper(II) glycinate in a typical tablet. Give your answer to three significant figures.
