A calorimeter holds 125 g water at 22.0°C. A 45 g sample of silver at 130.0°C is added to the water, and the final temperature of the water and silver is 24.2°C. The specific heat of water is 4.18 J/g°C. What is the specific heat of silver? Group of answer choices

0.241 J/g°C

2.16 J/g°C

51.8 J/g°C

558 J/g°C

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
