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.

Figure the fraction of box tops each class collected, then multiply the prize money by that fraction.
Total box tops = 3760 +2301 +1855 = 7916
Mr Coronado's class's fraction: 3760/7916 × $600 = $284.99
Mrs De Souza's class's fraction: 2301/7916 × $600 = $174.41
Mr Nost's class's fraction: 1855/7916 × $600 = $140.60
