Question

No.  Human error.

anonymous · Answer

It depends on the accuracy of the measuring device I suppose, as well as temperature and pressure.

mertsj · Answer

I suppose it depends on whether or not Tom and Pam read the measuring instrument in exactly the same way.

anonymous · Answer

Well, it does have a measurement mark, so it should be pretty close. It would never be the same number of atoms but it would be very close. if it wasn't graduated, then the difference would be much higher.

no - to within the level of the graduations
