3.26 g of Iron powder are added to 80.0 cm3 of 0.200 mol dm- copper (IT) sulfate solution. The following reaction occurs:
Fe (8) + CuSO4 (aq) → FeSO4 (aq) + Cu (S)
1a. Determine the limiting reactant showing your working.
1b. The mass of copper obtained experimentally was 0.872 g. Calculate the percentage yield of copper.

catya that's not even a b or 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
