A student determines the concentration of \(\text{Cu}^{2+}\text{(aq)}\) in a solution using spectrophotometry. The student transfers a \(10.0\text{ mL}\) sample of the original solution into a volumetric flask and adds distilled water to make \(100.0\text{ mL}\) of diluted solution. The absorbance of the diluted solution, measured at the wavelength of maximum absorbance in a cuvette with a path length of \(1.00\text{ cm}\), is \(0.240\). If the molar absorptivity (\(\epsilon\)) of the absorbing species at this wavelength is \(80.0\text{ M}^{-1}\text{cm}^{-1}\), what was the concentration of \(\text{Cu}^{2+}\text{(aq)}\) in the original solution before dilution?
