A 50-mL volumetric flask measures a volume of 50.00 mL. In this experiment, we want to show that this is true. 50.00 mL is the actual volume measured by this volumetric flask. ΕXPERIΜΕNT: The mass of an empty volumetric flask is measured. Then water is added to the volumetric flask and the meniscus is adjusted to be at the correct level. Then the mass of the volumetric flask and the water is measured. Finally, the temperature of the water in the volumetric flask is measured. RESULTS: Mass of empty volumetric flask = 37.04 g Mass of volumetric flask and water = 86.83 g Temperature of the water in the volumetric flask = 23°C 4 Densities of water at different temperatures: Density of Water at Different Temperatures (g/cm?)

PART 3 A Volumetric Flask + A С — ALI50 SOA A 50-mL volumetric flask measures a volume of 50.00 mL. In this experiment, we want to show that this is true. 50.00 mL is the actual volume measured by this volumetric flask. EXPERIMENT: The mass of an empty volumetric flask is measured. Then water is added to the volumetric flask and the meniscus is adjusted to be at the correct level. Then the mass of the volumetric flask and the water is measured.
