i have a Chemistry lab (level 2) final exam soon.

our teacher told us that we would have % transmittance problems, can someone show me an examples (maybe from an online test) or a made up one, of what i might expect to find on my chemistry lab final? like an examples of a % transmittance problem?

he just gave us this equation and told us we'll solve problems with it:
%T = I/IO x 100

I would look closely at your notes, I do not know what you studied in your class. But I suspect it was Beers Law, or Beers-Lambert
