Instructions: For this investigative phenomenon, you will need to determine the densities of an unknown solid and liquid using different methods of measurement to determine if the solid will float on water. Record your observations and test measurements in the lab report below.
WebThe hydrostatic method allows us to reduce uncertainty in measuring the density of objects with complex shapes by eliminating the need for a direct volume measurement. Instead we apply Archimedes’ Principle and the concept of static equilibrium to calculate the volume from measurements of the weight and apparent weight.
WebIgnoring any errors in measuring the volume, the density is calculated to be 4.088 g / 0.6 mL = 6.8 g/cm 3. (Note: 1 mL = 1 cm 3.)
