Help please worth 15days ? Question
Now build a model of salt. Use the blue, squarer marshmallows to represent the chlorine atoms and the
pink, rounder marshmallows to represent the sodium atoms. Connect the marshmallows with toothpicks
using the picture in part A as a guide.
Drag each image to the correct location on the model. Each image can be used more than once.

Explanation:

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
