The partition coefficient, Kp. at 25°C (1.e., room temperature) for compound A is 9.71 (for water and benzene). Starting with a solution of 16.6 g of compound A in 110 ml of water, what is the total percent of compound A that is extracted into the benzene after two successive extractions of 65.0 mL benzene each? (Enter a value with 3 sig figs and do not include the % sign)

There are several steps involved in the purification and isolation of benzoic acid from the Grignard reaction. During some steps benzoic acid itself is present (PhCO₂2H); in other steps it is present as the benzoate salt (PhCO2 Kt). Complete the sentence below by stating whether it is benzoic acid or benzoate salt present (first blank) and in which phase it is dissolved (second blank). In a mixture of ether and water after base has been added to the separatory funnel, O a. benzoic acid, aqueous O b. benzoic acid, ether c. benzoate salt, aqueous O d. benzoate salt, ether is present in the phase.OGMU 2021 K

1. If the temperature probe was mis-calibrated by +0.10 ˚C during both experimental procedure Part A and Part B,would the reported moles of biphenyl in the solution be too high, too low, or unaffected? Justify your answer .2. Consider the following errors that can occur during Part B of the experiment. How would each of these errors affectthe experimental molar mass of a solute (greater than true molar mass, less than true molar mass, unaffected)?Justify your answers.a. Some of the solid solute adhered to the side of the test tube during data collection. b. Some of the cyclohexane solvent vaporized during data collection. c. The solute dissociated slightly in the solvent.
