Answer #1

Discrepancy between results occur due to a number of causes and factors.Some of these things can be ignored /neglected by making reasonable assumptions.Assumptions are generally made to reconcile results in cases where the factors causing discrepancy cannot be eliminated to obtain precision and accuracy.Examples include air friction in many experiment.Air friction cannot be eliminated but it can be ignored to reconcile the known and calculated values.Other examples include gravity and earth rotation in some cases.

Early evidence for the existence of noble gases was the discrepancy between the apparent molecular mass of nitrogen obtained from the atmosphere (after removal of oxygen, carbon dioxide, and water vapor) and that obtained from the decomposition of ammonium nitrate to nitrogen and water. Results: 28.01 g/mol (pure N2) 28.15 g/mol (N2 contaminated with Ar) If the discrepancy is solely due to argon (MM = 39.95 g mol-1), what is the nAr/nN2 in the atmosphere?
