Weighing a Sample

 

Video. Weighing.

Procedural outline:

  1. Block air currents from the balance pan by closing or assembling the draft shield.
  2. With nothing on the balance pan, press the tare button to set the digital display to zero.
  3. Place an empty weighing vessel on the balance pan, observe the mass from the digital display, and record the mass of the empty weighing vessel.
  4. Remove the weighing vessel from the balance pan and add the sample for which you need to know the mass.
  5. With nothing on the balance pan, press the tare button again to confirm that the initial mass reading is zero.
  6. Place the weighing vessel that contains the sample on the balance pan, observe the mass from the digital display, and record the mass of the weighing vessel and sample.
  7. Calculate the difference between the mass of the weighing vessel that contains the sample and the empty weighing vessel. The difference is the mass of the sample. (Mass of sample) = (Mass of weighing vessel and sample) - (Mass of weighing vessel)
