Write a 200 word summary paragraph discussing this experiment and the results. Use the following questions and topics to help guide the content of your paragraph. What happened to the cabbage indicator when breath was bubbled into the water? Why? What happened to the cabbage indicator in the club or clear soda? Why? Explain the connection between your observations and data and the pH of the oceans. Give at least one example from real life where the principles demonstrated in this lab are evident.

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

c. 4.54 x 10–12 j happens to be correct
