Calcium hypochlorite ( ca(ocl)2ca(ocl)2 , mw = 142.983 g/mol) is often used as the source of the hypochlorite ion ( ocl−ocl− , mw = 51.452 g/mol) in solutions used for water treatment. a student must prepare 50.0 ml of a 20.020.0 ppm ocl−ocl− solution from solid ca(ocl)2ca(ocl)2 , which has a purity of 92.092.0 %. calculate the mass of the impure reagent required to prepare the solution. assume the density of the solution is 1.00 g/ml.

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
