As the lab instructor for Cell Bio, you need to make a solution of DCMU, an inhibitor of photosynthetic electron transport. You want a final concentration of 2×10^-5 M in a final volume of 1.25 mls, and this needs to be achieved using a 10 microliter shot from the pipet. How much DCMU should you weight out to dissolve in 10 mls of alcohol? The MW of DCMU is 400 g/mole.
