Solute S has a distribution constant of 5.1 between water (phase 1) and hexane (phase 2). A 71.0 mL solution of S in water is extracted three times with 12.0 mL of hexane. Calculate the fraction of S remaining in the aqueous phase.

In an organic chemistry lab, some camphor crystals were synthesized but there were some traces of isoborneol also present in the crystals which lowered the melting point of the camphor crystals from 179 °C to 169 °C. Treating it as a solid-solid solution with isoborneol as the solute and camphor as the solvent, find the mass percentages of camphor and isoborneol in the solution. The freezing point depression constant for camphor is 40 °C kg mol1. The molecular weights of camphor and isoborneol are 152.2 g/mol and 154.3 g/mol respectively. O A. 96.14 % and 3.86 % respectively B. 3.80 % and 96.20 % respectively O C. 3.67 % and 96.33 % respectively O D. 96.29 % and 3.71 % respectively O E. 99.75 % and 0.25 % respectively

Given the following mixture of two compounds 70.00 mL of X (MW =80.00 g/mol)(density 0.800 g/mL) and 820.00 mL of Y (73.00 g/mol))(density 1.056 g/mL). The freezing point of pure Y is 17.00 degrees C. The molal freezing constant is 3.091 degrees C/m. What is the freezing point of the solution, in degrees C?

Solute S has a distribution constant of 4.9 between water (phase 1) and hexane (phase 2). A 89.0 mL solution of S in water is extracted five times with 14.0 mL of hexane. Calculate the fraction of S remaining in the aqueous phase. fraction remaining:
