To determine the buoyancy (or Archimedean) force, you need to know the following formula:
F = g * ρl * Vt (F-Archimedean force; g-acceleration of gravity (9.8 N / kg); ρl-density of the liquid, in this case alcohol (800 kg / m3); Vt-body volume (25 cm = 0.25 m).
F = 9.8 * 800 * 0.25 = 1960 H
Answer: F = 1960 H
