Solved: Complete hydrolysis of a 100.00-g sample of a peptide gave the following amounts
Chapter 15, Problem 15.120(choose chapter or problem)
Complete hydrolysis of a 100.00-g sample of a peptide gave the following amounts of individual amino acids (molar masses, in g/mol, appear in parentheses): 3.00 g of glycine (75.07) 0.90 g of alanine (89.10) 3.70 g of valine (117.15) 6.90 g of proline (115.13) 7.30 g of serine (105.10) 86.00 g of arginine (174.21) (a) Why does the total mass of amino acids exceed the mass of peptide? (b) What are the relative numbers of amino acids in the peptide? (c) What is the minimum molar mass of the peptide?
