What do you think about synthesis and spectrophometric analysis of aspirin lab and brief summary about these results please thank you!! ### Graph Explanation**Title**: Absorbance vs. ConcentrationThe graph displays the relationship between absorbance and concentration for salicylic acid standard solutions. The x-axis represents the concentration in mol/L, ranging from 0 to 4, while the y-axis shows the absorbance values from 0.1 to 0.7. **Data Points and Line**:- There is a scatter plot representing various measurements of absorbance at different concentrations.- A trend line is fitted to the data, following the equation: \( y = -0.1803x + 0.7965 \). This line indicates a negative correlation between absorbance and concentration.**Statistical Information**:- The coefficient of determination, \( R^2 \), is 0.9892. This value is close to 1, suggesting a strong correlation and that the line of best fit accurately represents the data.**Figure Note**:- Figure 1 is labeled as the "Beer’s Law Calibration Curve for Salicylic Acid Standard Solutions," depicting how absorbance decreases with increasing concentration.This graph is part of an educational material illustrating the principles of Beer’s Law, which describes the linear relationship between absorbance and concentration of a solution. **Data Analysis on Salicylic Acid and Aspirin**### Table 1. Beer’s Law Data for Salicylic Acid Standard Solutions| Trial | Concentration (mol/L) | Absorbance ||-------|----------------------|------------|| 1 | 5.79 x 10^-4 | 0.631 || 2 | 4.63 x 10^-4 | 0.403 || 3 | 3.48 x 10^-4 | 0.277 || 4 | 2.32 x 10^-4 | 0.72 |### Table 2.
