Consider two immiscible liquids such as water and oil. If a spherical oil molecule of radius r is taken out of the oil phase and placed in the water phase, the unfavorable energy of this transfer is proportional to the area of the solute (oil) molecule newly exposed to the solvent (water) multiplied by the interfacial energy, i, of the oil-water interface. The interfacial energy of the bulk cyclohexane-water interface is i = 50 mJ m-2, and the radius of a cyclohexane molecule is 0.28 nm. Using Boltzmann distribution, estimate the solubility of cyclohexane in water at 25 C in units of mol L-1.The concentration of water in water phase is 55.5 mol L-1.
hello what sort of calculator did you use? i am using ti 84 and ti 89 still not getting the answer even when i use you numbers. i am a bit confused about that.
The average electricity consumption of a house in
Gainesville is known to be 1,036 kWh in a month
(One month = 30 days). They would like to install
solar panels of 30 % efficiency to generate this
electricity. Given that the average solar power
density in Gainesville is 5.47 kWh/m2/day, how much
surface area must the panels occupy? Calculate the
result in m² but do not write the unit. Round off you
E swer to a whole number (zero decimal place.)
