You are given 150 mL of an oil made up of a mixture of 3 fatty acids: palmitoleic acid (C 16:1 (n-7)) erucic acid (C 22:1 (n-9)) stearidonic acid (C 18:4 (n-3)) You know that the 150 mL sample of this oil was prepared by adding 60 mL of palmitoleic acid to 90 mL of a mixture of erucic acid and stearidonic acid. Using a hydrometer you carefully measure the density of the 150 mL sample of oil and your analysis indicates that it has a density of 0.900 g/cm3. The densities of the individual fatty acids are: palmitoleic acid = 0.894 g/cm3 erucic acid = 0.860 g/cm3 stearidonic acid = 0.9334 g/cm3 Can you determine the volumes (in mL) of erucic acid and stearidonic acid in the total volume (150 mL) of the oil mixture?

You are given 150 mL of an oil made up of a mixture of 3 fatty acids:
- palmitoleic acid (C 16:1 (n-7))
- erucic acid (C 22:1 (n-9))
- stearidonic acid (C 18:4 (n-3))
You know that the 150 mL sample of this oil was prepared by adding 60 mL of palmitoleic acid to 90 mL of a mixture of erucic acid and stearidonic acid.
Using a hydrometer you carefully measure the density of the 150 mL sample of oil and your analysis indicates that it has a density of 0.900 g/cm3.
The densities of the individual fatty acids are:
- palmitoleic acid = 0.894 g/cm3
- erucic acid = 0.860 g/cm3
- stearidonic acid = 0.9334 g/cm3
Can you determine the volumes (in mL) of erucic acid and stearidonic acid in the total volume (150 mL) of the oil mixture?
