question 4 please and write a short conclusion about the graph

and please check if the drawn graph is correct according to the data

need to find the concentration of unknown solution from the calibration curve

1. Set the wavelength at ( max). Place the cuvette with distilled water in the cell compartment and again set the Absorbance to zero. 2. Measure and record the Absorbance of each of the four standard solutions, starting with the most dilute standard. 3. Draw a plot having X-axis as concentration (mole/L) and Y-axis as Absorbance at max. 4. Find concentration of unknown solution from calibration curve. 313.00nm1.0507A \begin{tabular}{|l|c|} \hline \multicolumn{1}{|c|}{ Samples } & \\ \hline & \\ \hline & 313nm \\ \hline 0.1M. Sample (A) & 3.8859 \\ \hline 0.01M. Sample (A) & 2.1138 \\ 0.001M. Sample (A) & 0.1112 \\ 0.0001M.Sample (A) & 0.0073 \\ Unknown. Sample (A) & 1.0503 \\ \hline \end{tabular} 1.
