I'm trying to figure out the number density (molecules/unit volume) of the dye for a sample of dye doped PMMA. The information I have is that the dye makes up 1% by weight of the mixture used to make the sample. I also have the chemical structure of the dye. I looked up the structure of the PMMA and found it here: http://www.psrc.usm.edu/macrog/pmma.htm , but I don't understand what the brackets around the [tex]CH_2-C[/tex] group signify.
