Why would a repeating unit of PET (polyethyleneterephthalate) be used to calculate the limiting reagent and...

Why would a repeating unit of PET (polyethyleneterephthalate) be used to calculate the limiting reagent and yield instead of the molecular weight of the polymer? Is it just because it is a polymer and only its monomer needs to be taken into account?

When performing a REAGENT BLANK in chemistry, do you add or subtract the volume of the blank determination from the volume of titrant to get the corrected volume of titrant used? In this particular experiment we are determining Ca2+ and Mg2+ in natural water samples. And, do you always add or subtract the blank reagent or does it change with reactions? Probably simple questions but they have me completely stumped. Thanks!

In an experiment, why would the concentration of a sample decrease when changing the wavelength for a spectrophotometer from 235 nm to 280 nm? This is just a general question, I would like to know why the absorbance peak would be higher at a wavelength of 235nm rather than at 280nm. Is this normal? or could it an experimetnal error?
