Calculating the Molecular Weight of Glucose Polymers

[doc.madani]

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?

 

[doc.madani]

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.
