It is given that a protein has a molecular weight (Mw) of 21342. It consists of 180 amino acids of which 80 are glutamine (Mw of anhydro residue = 128.1), 60 are histidine (Mw of anhydro residue 137.2) and 40 alanine (Mw of anhydro residue 71.1). At both the C-terminal and the N-terminal position an alanine residue is present.

they both have a y in them

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
