this is a question for a lab experiment...in the lab we got 2 empty vials and were supposed "eyeball" 1.0g of NaCl into each of the vials using a vial with NaCl in it already as a sample. Then we weighed the filled vials on analytical balance and recorded weight. Then we emptied the vials and weighed them on the analytical balance.
The question is:
why is the "empty" vial weighed after pouring the sodium chloride out of the vial, instead of before putting the sodium chloride into the vial?

    You need to tell me more about the experiment. Perhaps another volunteer has some experience with an experiment of this type and can chime in. What did you do with the data? What was the purpose of the experiment?

    If you wanted to know what amount of sodium chloride was delivered into another container, you would weigh the vial with the salt in it, then weigh the "empty" container which may have traces of salt stuck in it.
