Initial data: V (volume of mercury) = 4 l (0.004 m3).

Reference values: ρ (tabular value of mercury density) = 13600 kg / m3; g (acceleration due to gravity) = 9.81 m / s2 ≈ 10 m / s2.

1) We calculate the mass of mercury with a volume of 4 liters: m = ρ * V = 13600 * 0.004 = 54.4 kg.

2) Determine the force of gravity that acts on mercury: Ft = m * g = 54.4 * 10 = 544 N.

Answer: The gravity force of 544 N acts on 4 liters of mercury.
