1. You have a 2.5 mg/ml result of an amino acid (mol.wt. = 100). You are essential to add 0.5 µmoles to a test tube. How much would you pipette?

2. You want a 10mM solution of a potent (and dangerous) transcription inhibitor (mol.wt.500) for an experiment. To avoid treating the powder form of this compound you decide to make up the whole bottle rather than attempt to weigh out a portion. The compound comes in 200 mg batches. What capacity would you add to one of these bottles to make up a 10 mM solution?
