**Preparation of Dilute Solutions from Stock Solutions**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. **Problem Statement:**What volume of a 0.0015 M solution of MgCl₂(aq) would be required to prepare a 73 nM solution of Mg²⁺ in a 150 mL flask?**Options:**- 1.5 µL- 7.3 µL- 15 µL- 0.53 µLThis exercise involves calculating the correct volume of the more concentrated stock solution needed to achieve the desired lower concentration in a specified volume, using the dilution formula.

Molarity of a solution is defined as the moles of solute present in one litre of solution. It is…
