Unformatted text preview: water and transfer to the weighing bottles. I recorded the new weight of the weighing bottles with the water and the temperature of the wash bottle. After careful calculations, I came out with an average volume of 9.96-mL delivered by the pipet to the weighing bottles. The relative average deviation for the volume delivered by the pipet came out to be 0.40%. Because I received a %RAD greater than 0.2%, this means that I have not mastered the use of the pipet as mentioned in the lab manual. However the average volume delivered of 9.96-mL sounds reasonable as mentioned by Professor Pang in lecture. Some of the errors that I might have encountered include not cleaning the pipet and weighing bottles completely, not using the analytical balance properly, and/or not making precise measurements. However, I think that practicing to use the pipet will help me make more precise measurements in later experiments involving the pipet....
