The chances that a work of art from ancient times will be found or preserved are greatly increased if it was made of durable materials. the local climate is conducive to preservation. the culture from which it came was stable and organized. it was located where access from the outside world was limited. all of the answers are correct.

If the work of art from ancient times was made of durable materials, it was located where access from the outside world was limited, the local climate is conducive to preservation and the culture from which it came was stable and organized it will have the chance that it will be found or preserved are greatly increased.

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
