Answer:
Percentage of mass of solute in aqueous phase is 28.57%.
Explanation:
- Fraction of solute in aqueous phase.

= Used volume of aqueous solution
= Used volume of organic solution
D = partition coefficient.

Mass of solute in aqueous phase = 

Therefore, Percentage of mass of solute in aqueous phase is 28.57%.
I believe that it most likely would be D.
Answer: d = 7.9 g/cm^3
Identify the given information.
m = 79 g
v = 10 cm^3
Choose which formula you should use. In this case, you are finding the density.
d = m/v
Substitute and solve.
d = 79 g/10 cm^3
d = 7.9 g/cm^3
