Question 46 (5 points) How much time is required to inject a sample equal to 2.0% of the length of a 60 cm capillary if the diameter is 50 um and the pressure difference is 2.0x104 Pa (0.20 bar)? Assume the viscosity is 0.0010 kg/(m.s), which is close to the viscosity of water. Note: The units work out when we realize that Pa = force/area = (kg m/s2)/m2 = kg/(m.s2). RA B I VA E Paragraph E OP + ... Question 47 (5 points) Solute A has a partition coefficient of 4 between toluene and water, with four times as much in the toluene phase. Suppose that 132 mL of a 10.2 M aqueous solution of A is extracted with toluene. What fraction of A remains in the aqueous phase if one extraction with 751 mL is performed or if five extractions with 50.0 mL are performed? Paragraph 00 B IU A blo + 24
