An analytical balance is used to measure the mass of a substance
Always record your data to the precision of your instrument (remember trailing zeroes are significant)
- Fold weighing paper in half to make a triangle and crease it
- Place unfolded weighing paper on a clean and dry balance pan and close the side doors
- Wait for the mass to stop changing (or green triangle appears)
- Press "tare" button (should read 0.0000g)
- Open door and use spatula to add substance up to desired mass
- Close the side doors and record the mass once the scale has stabilized
- Clean the balance pan and area, properly discard weigh paper
