16. Examine the boxes below. Both boxes are identical to one another. The mass of each box is concentrated in the very center, so the center of mass is in the middle of the box.
(Remember that mass is similar to weight.) The arrows represent gravity pulling down on
the center of mass of each box. Which of the boxes represents a stable system? If you were
to give that box a small push, what would happen to its state of equilibrium? Describe how
a disturbance to this box would affect it. Use the terms center of mass and equilibrium in

the ratio of the conjugate base to the acid required to attain the desired ph.

the right answer is c i just did the question.

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
