Calculate the weight percentage of phenol and draw the relationship with it. The weight percentage of phenol and the rate for a binary system consisting of water + phenol, where the weight of phenol is equal to (3g), and (12lm, 10lm, 8lm, 6lm, 4lm) of distilled water was added to it at each reading, and the temperatures were recorded. For mixing and turbidity as follows: Mixing temperature Turbidity temperatur 25 45 30 40 35 35 40 30 45 25

4. Pure octane has a boiling point of 125.7 °C, but can be steam distilled with water at a tem- perature of 90 °C. Calculate the mass of octane that codistills with each gram of water and the percent composition of the vapor that is produced during the steam distillation. [Again, you'll need the vapor pressure of water at the steam distillation temp to solve this problem!] Note that if you multiply the second equation from question 3 above by the MW of both the oil and water, you get: mass oil/mass water = (P°) (MW)/ (Pwater) (MW water)
