SUMMARY

The discussion focuses on the extraction of cholesterol from egg yolk using the Soxhlet Method with dichloromethane as a solvent. The experiment involves crushing half a boiled egg yolk and adding 80 cm³ of dichloromethane. A key question raised is how to quantify the cholesterol concentration, assuming maximum absorption at 550 nm, which indicates the need for a visible light spectrometer for measurement.

PREREQUISITES

Homework Statement



During an experiment using Soxhlet Method to extract cholesterol from egg yolk, also using dicloromethane as a reagent, we crush half boiled egg yolk and put 80 cm3 of dicloromethane.

Homework Equations



Then comes a question which is assuming the maximum of absorption of the reagent-cholestrol is 550 nm, sugest a way to quantify it.

The Attempt at a Solution



I don't understand what should I answer here

As worded it doesn't make much sense. Obviously it is about measuring concentrating using visible light spectrometer.
