What is the density of a sodium chloride solution if a body with a volume of 200 cubic cm pushes out of the solution with a force of 2.26 N?
To find the buoyancy force, you need to know the formula: Fа = g * ρж * Vт (Fа-buoyancy force (2.26N); g-acceleration due to gravity (10N / kg); ρl-density of the liquid; Vt-body volume (200cm3 = 0 , 0002m3)).
Therefore, to find the density of the liquid, you need: ρ = Fa: (g * Vt)
ρ = 2.26: (0.0002 * 10) = 2.26: 0.002 = 1130 kg / m3
