Aldol Condensation: The Synthesis of 2'-Hydroxy-4-methoxychalcone 25 mg of your product and dissolve in MeOH (50 mL) using a 50 mL volumetric flask- stock solution. Take 0.5 mL of the stock solution and make up (in a volumetric flask) to 25 mL- Solution A. Take 5 mL of solution A and make up to 25 mL with MeOH - solution B- and record spectrum. Then take 1 mL of solution A and make up to 25 mL with MEOH – solution C- and again record spectrum. Plot the value of the absorbance at the Amax versus concentration and using the Beer-Lambert relationship (Abs ecl) calculate the extinction coefficient (ɛ) and please show graph
