In this lesson, you'll be learning the wing by different technique. Into this technique, we are going to weigh 5 grams of the solid. So far are the apparatus that you need. A wing balance, a waist-bigger, a clean beaker, a wing bottle that is clean and dry, and a clean spatula. First, ensure that all the windows are closed and care the wing balance. Next, put the wing bottle in and tap. Next, we'll fill the wing bottle with the solid. If you have exceeded the weights that you need, take out the wing bottle and dispose any unwanted solid into the waist-bigger. Once you have reached the weight that you want, take out the wing bottle, close the window of the wing balance and tap. After that, put back the wing bottle with the solid in and take the reading of the wing balance. This reading would be the mass of the wing bottle and sample that you need to record in your lead report. After you are done, transfer the solid from the wing bottle into the clean beaker. Make sure you tap the wing bottle to transfer all the solid into the beaker. After this is done, tear the wing balance again. Place the wing bottle back into the wing balance. The reading that you see on the wing balance would be the mass of the wing bottle and residue, and you will need to record this reading in your lead report. After this is done, subtract the second reading from the first reading, and the value that you get would be the mass of solid use in the experiment.
