The volume of a sphere:

$\overline{){\mathbf{V}}{\mathbf{=}}\frac{\mathbf{4}}{\mathbf{3}}{\mathbf{\pi}}{{\mathbf{r}}}^{{\mathbf{3}}}}$

Density:

$\overline{){\mathbf{\rho}}{\mathbf{=}}\frac{\mathbf{m}}{\mathbf{V}}}$

Neutrally buoyant implies that the ball and the liquid have equal densities.

A 6.00cm -diameter sphere with a mass of 89.3g is neutrally buoyant in a liquid. Identify the liquid.
