The discussion revolves around calculating the number of free electrons in sodium using resistance data and the Drude model. Participants are exploring the relationship between resistivity and free electron density.
Some participants have provided guidance on using resistivity values and suggested methods for finding the number of atoms per cubic centimeter. There is an acknowledgment of progress on the first part of the problem, but uncertainty remains regarding the second part.
Participants note the need for specific units and mention the importance of looking up resistivity values. There is a reference to homework posting guidelines.
Yea I was using the drude model. I know the value of resistivity of sodium to be 4.2Exp-6nasu said:Just use the formula for resisitvity. Probably you are using the Drude model.
And you need to look up the value of resistivity.
And better post this in the homework section.
I was able to solve the 1st part but he second part (per atom) kind of eludes menasu said:Then what is your problem?
Some units won't hurt.
Oh, you can find the number of atoms per cubic cm from density and atomic mass.eforma said:I was able to solve the 1st part but he second part (per atom) kind of eludes me
