how does the sample mass determined by explicity subtracting the mass of the container compare to the determined using the electronic tare function?
how does the determined mass of a sample depend on the mass of a container ? does the anwer to this question depend on wheter the electronic tare function is used?
Solution
The procedure to weigh a sample that is on a container is the following: 1) Make sure that the balance is at zero. 2) Weigh container. 3) Record the weight of the container. 4) Remove the container, place sample and re-weigh container + sample. 5) Subtract weight: Container + shows less Weight: Container. In the case of electronic tare, it is not necessary to note the weight of the container since the balance registers it. Using the electronic tare, a greater precision is obtained, since human error is eliminated. For very heavy containers and very small samples, and scales of little appreciation, the weight of the container may be a problem, since it would not allow registering the correct weight on the balance.
