Problem
In microcentrifuge tubes and using 95% ethanol as the diluent, make the following solutions from the 20 mM HABA stock solution: 2 mM, 400 µM, 200 µM and 20 µM. Try diluting in series use the 20 mM HABA to make the 2 mM, the 2 mM to make the 400 µM. Make each solution in a final volume of 200 µL show your work
