Question
Why did you measure 60 ml and not 59.04 ml to make up this final solution?
![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.
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
To get to your experimental conditions you combine the following 2 liquids (consider the final
volume of this mixture = 60 ml for your calculations).
