Measurer the initial amount of water that is in the pipet. e. Release some of the water into an empty beaker and record the final volume in the pipet. f. Record the final mass of the beaker that you just added water to. g. Repeat steps “a” through “f” two more time. h. Repeat steps “a” through “g” using a graduated cylinder instead of a pipet i. Repeat steps “a” through “g” using a beaker instead of a pipet. 2. The Measured Density of Water at Room Temperature.
