The molar mass of cellulose is approximately 6.0x 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 molar mass of cellulose is approximately 6.0x 105g/mol and the molar mass of a soluble starch is on the order of 4.0 x 103g/mol.  The monomer unit in both of these molecules has the empirical formula C6H10O5. The units are about 5.0 x 10-10m long.  About how many units occurs in each molecule, and how long are the molecules of cellulose and starch as a result?
