In order to determine the oil content of different types of potato crisps (chips), a student weighed 5.00g of crushed crisps and
mixed them with 20.0cm3 of non-polar solvent. She assumed all the oil in the crisps dissolved in the solvent.
The student then filtered the mixture to remove any solids, and gently heated the solution on a hot plate to evaporate the solvent.
She measured the mass of the oil that remained from each type of crisps
Suggest why a non-polar solvent was needed.
