c) Benzene is one of the Toxic Air Pollutants (TAPS) found in can exhaust fumes. When a 50.00 mL aqueous sample containing a 0.05000 M benzene (molecular weight = 78.11g/mol) is extracted twice with 10.00 mL portions of chloroform, it is found that 1.50 x 10 moles of the original compound has been extracted into the chloroform. i. Calculate the value of the partition coefficient for the extraction of benzene in water using chloroform [3 marks] [3 marks] ii. How much is the extraction efficiency of a single extraction? iii. Determine the total volume of the chloroform which will be needed to extract 99% of the benzene from the aqueous phase. [6 marks]
