Answer:
   C.  0.006 g/cm³
Step-by-step explanation:
As the units tell you, density is the ratio of mass to volume. The volume of the container is found from ...
   V = πr²h = π(10 cm)²(25 cm) = 2500π cm³
Then the density is ...
   ρ = (50 g)/(2500π cm³) = 1/(50π) g/cm³
   ρ ≈ 0.006 g/cm³

<em>Comment on the problem</em>
The "liquid" has about the same density as air pressurized to 75 psi.
