What is the working solution and DI water of the unknown solution?

 

power to electrical signals. Calculation 1: Erioglaucine (Molar mass 792.85 g/mol) is an intense blue dye with maximum absorption (Amax = 625 nm). An experiment was done in the laboratory which resulted the following data: %3D Erioglaucine H3C N. O=$=0 Na O=S=0 A stock solution of Erioglaucine was prepared by dissolving 0.198 g Erioglaucine in a volumetric flask with a volume of 250 ml. The stock solution is then diluted to a second (more diluted solution) called eworking solution by taking 2.50 ml of stock solution and dilute it into 250.00 ml. With this working solution the following five solutions were prepared and their absorption was measured at 625 nm. Na N.
