A student measures the absorbance of a solution of \(\text{Co(NO}_3\text{)}_2\text{(aq)}\) using a spectrophotometer set to the wavelength of maximum absorbance, \(\lambda_{\text{max}} = 510 \, \text{nm}\). The sample has a concentration of \(2.50 \times 10^{-3} \, \text{M}\) and is placed in a sample cuvette with a path length of \(0.500 \, \text{cm}\). The measured absorbance is \(0.600\). Based on these data, what is the molar absorptivity, \(\epsilon\), of \(\text{Co(NO}_3\text{)}_2\text{(aq)}\) at \(510 \, \text{nm}\)?
