help pls answer only if you know where to put them, PLEASEEE DO NOT ANSWER FOR THE POINTS I'VE ASKED THIS QUESTION LIKE A LOT OF TIMES ALREADY AND ALL OF Y'ALL ONLY ANSWER FOR POINTS COULD YOU PLEASE NUMBER WHERE EACH ONE GOES LIKE THE ONES THAT ARE IN RED IN THE CORNER, LET ME KNOW WHERE TO PUT THEM JUST NUMBER THEM

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8

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
