Glucose Monomer

  1. Mar 22, 2010 #1
    Glucose (C6H12O6) is a monomer that can form naturally occurring polymers.
    What would be the approximate molecular weight of a polymer made from 5 glucose monomers?

    a) 810
    b) 828
    c) 882
    d) 900

    i said D, but my friend in convincing me its B :S

    What happens when two glucose molecules bond together to form a disaccharide?

    is it cellulose, in which the water molecules are condensed out. therefore you will need to subtract the molar mass of the water molecules from 900 ? hence the answer is B ??

    Well, I'm not sure that it's necessary cellulose (which to me is a specific condensation, and perhaps more than 5 monomers), but yes, that's the idea.
