What is the density of a solution of sodium chloride if a body with a volume of 200 cm3

What is the density of a solution of sodium chloride if a body with a volume of 200 cm3 pushes out of the solution with a force of 2.26 N.

Data: V is the volume of the body immersed in the specified solution (V = 200 cm3 = 2 * 10-4 m3); FA – buoyancy (Archimedean) force (FA = 2.26 N).

Const: g – acceleration due to gravity (g ≈ 9.8 m / s2).

To find out the density of the specified sodium chloride solution, we apply the formula: FA = ρр * g * V, from where we express: ρр = FA / (g * V).

Let’s calculate: ρр = FA / (g * V) = 2.26 / (9.8 * 2 * 10-4) ≈ 1153 kg / m3.

Answer: The density of the specified sodium chloride solution is 1153 kg / m3.
