The molar mass of cellulose is approximately 6.0 x 105 g/mol and the molar mass of a soluble starch is on the order of 4.0 x 103 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?
