Constant burette reading
WebJan 5, 2024 · The correct reading is 19.50 mL. Due to parallax error, the reading can be 19.62 mL or 19.42 mL. The first and final reading of the burette should be recorded. The difference between the first and final reading is called the titer. Readings should be recorded to the nearest 0.05 mL. Examples of readings: 22.05, 23.00, and 23.05 mL. Webλ in m=669.8 nm× (1 m/1×109 nm) Then substitute the wavelength into the equation. E=hc/λ= (6.626×10−34 J-s) (2.998×108 m/s)/ λ in m.
