Answer:
Specific rotation of cholesterol is -3.15°.
Explanation:
Given that
Path length = 10 cm = 1 dm.
Observed rotation ,α= - 0.441 °
m= 0.14 g
V= 1 ml
The concentration of cholesterol ,c= m/V g/ml
c = 0.14 / 1 = 0.14 g/ml
We know that specific rotation given as
Now by putting the all values
°
Specific rotation of cholesterol is -3.15°.
