2. You want to do an experiment on cells to treat them with very low concentrations of both Atrazine and DMSO (which is the solvent you need to use to make your atrazine stock solution). To do this you must first make a relatively concentrated stock of atrazine (3 x106 ppm Atrazine, DMSO) by dissolving powdered atrazine in DMSO. a. You have 0.6 g of Atrazine left in the bottle, how much (3 X 106 DMSO) can you make? ppm Atrazine, Next you use the (3 x106 ppm Atrazine, DMSO) stock to make a less concentrated solution by combining: 1 μL of (3 X 106 ppm Atrazine, DMSO) 0.999 ml of cell culture media b. What is the concentration of Atrazine in this new solution in ppm units? c. What is the concentration of DMSO in %v/v units?
