What sort of a person designs a lab protocol so that liquid chemicals are reported in moles?

The recipe *could* have just told me how many milliliters of beta-mercaptoethanol I needed to add to my buffer. But, oh no, that would be too easy. So much more satisfying to tell me how many moles I need – thus requiring me to look up the chemical’s formula weight and density and do all sorts of obscene calculations in which none of the units seem to cancel out properly after a long day in the lab without proper snacks and caffeine.

It’s not as if I’ll ever need to perform this experiment on the Moon.


As you were.
