Question

15. The container shown in the figure is filled with a liquid that weighs 50 g. Find its density.

A. 5 g/cm3
B. 7900 g/cm3
C. 0.006 g/cm3
D. 157 g/cm3

Answer 1

Can someone confirm is this answer is right?

Answer 2

C. 0.006 g/cm³

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

Comment on the problem

The "liquid" has about the same density as air pressurized to 75 psi.
