The relative volumes of chloroform and water that should be used is 9:10
Concentration of solution in chloroform = ( moles of chloroform )
Concentration of solution in water = ( moles of water )
Dissociation constant at ;
Concentration of solution in chloroform / Concentration of solution in water
Meaning;
Since mole is present in chloroform and
mole is present in water, Total mole of Caffeine present is
Now, we substitute our given values into the equation
Therefore, the relative volumes of chloroform and water that should be used is 9:10
