The molar mass of cellulose is approximately 6.0 x 10^5 g/mol and the molar mass of a soluble starch is on the order of 4.0 x 10^3 g/mol. The monomer unit in both of these molecules has the emperical formula C6H10O5. The uits are about 5.0 x 10^-10 m long. About how many units occur in each molecule, and how long are the molecules of cellulose and starch as a result?
