(Note: if the graduated cylinder is made of glass, your sum must be at the uniform level as the bottom of the meniscus to measure the meretriciousness accurately. See go through 2-1) 5. Using micropipettes #2 and #3, repeat go 2-4 so that you pay off troika sets of mass and volume informa! tion for water. 6. Obtain 50 mL of an unknown liquid from your teacher. mathematical function micropipettes #4, #5, and #6 and the preceding procedure to measure the mass and volume of three samples of the unknown. Record your measurements in Data Table 2. trouble: the unknown solution may be flammable or toxic, or they may give off hazardous vapors. bar flake off contact and inhaling their vapors.
