For the analysis of trace metals it is necessary to prepare solutions of very low concentrations from a stock solution of higher concentration using a micropipette and a volumetric flask. What volume of a 0.0030 M solution of MgCl2(aq) would be required to prepare a 15 nM solution of Mg2+ in a 450 mL flask? O 2.3 HL O 0.45 HL O 35 HL O 3.0 HL
