Use the Henderson- Hasselbalch equation to calculate the pH of
each solution.
a. a solution that is 0. 145 M in propanoic acid and 0. 115 M in
potassium propanoate
b. a solution that contains 0.785% C5H5N by mass and
0.985% C5H5NHCI by mass
c. a solution that contains 15.0 g of HF and 25.0 g of NaF in
125 mL of solution

whats the meaning of /

thats how its supposed to be

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
