Lab 4 in Chem 115 has three parts all calculating density. In part one, a 100 mL beaker, a volumetric pipet, and an analytical scale were obtained. To begin, the mass of the beaker was taken using an analytical scale. Then, 10.0 mL of an unknown liquid was transfered to the beaker using the volumetric pipet. Next, the mass of the beaker and liqiud was recorded along with the letter identifying the unknown liquid. By subtracting the mass of the 100 mL beaker from the mass of the beaker and liquid, the mass of the liquid was collected. Lastly, the density of the unknow liquid was found by dividing the volume of the liquid from the mass of the liquid.
A small regularly shaped solid and an analytical scale were obtained for part 2 of Lab 4. First,
