» Can you explain how separate stock solution can avoid biased estimations? and what are the bias estimations that happen regarding this sentence, if we use the same stock solution ?

If you just used one weighing, and weighed too little material you would decrease the signal to noise, and potentially make the assay appear less precise/accurate. Conversely weighing too much material would increase signal to noise and make the assay appear more precise. Having two weighing's makes it more likely to spot that issue.
