Lab 5. Measuring the density of liquids

To determine the density of an unknown liquid, a spherical metallic mass of diameter $d = 2.12\text{ cm}$ is utilized. The measured mass of the sphere in air is $m_{\text{air}} = 126.75\text{ g}$, and its apparent mass when fully immersed in the liquid is $m_{\text{app}} = 122.18\text{ g}$.

a)

What is the buoyant force exerted by the liquid on the immersed sphere?

b)

Calculate the density of the liquid.
