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.
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

CHEMISTRY
Calculating Density
Density is the compactness of matter. Density describes the quantity of matter (mass)
per unit of volume (3-dimensional space). Density is calculated as the mass of the matter
divided by volume.
The symbol for density is Greek letter rho (p). The units for mass are in grams (g) and the
units for volume is cubic centimeter (cm³). It should be noted that 1 cm³ is equal to 1 ml
of volume. 1 cm³= 1 ml. The units for density are g/cm³.
Part 1
Determine the density of the new liquid materials created in the Secret Density Research
Laboratory. Type the value (no units) of the density into the boxes in the density column.
Report density to the 2nd number after the decimal. Use a zero to the lef of the decimal for
values less than 1.00. Examples: 2.35, 0.75, 1.90
