Errors
- A potential error is the assumption of a monomolecuar layer.
- Another error is the assumption of 226 g/mol as the molecular weight of the oil.
The number of molecular layers and the molecular weight of the oil are multiplied together
and so an increase in one or both is needed. Since 226 g/mol seems to be a reasonable
size we can focus on the number of layers.
How many layers are required to give the correct answer?
