Lysine is an amino acid which has the following elemental composition: C, H, O, N. In one experiment, 2.175g of lysine was combusted to produce 3.94g CO2 and 1.89 H2O . In a seperate experiment, 1.873g of lysine was burned to produce 0.463g NH3. The molar mass of lysine is approximately 150g/mol. Determine the empirical and molecular formula of lysine.
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 empirical formula C6H10O5. The units 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?
