When a block is completely submerged under water, the buoyancy force on it is 11.8N; when it is completely submerged under an unknown liquid, the buoyancy force is measured to be 7.8N. What is the density (in unit of kg/m3) of the unknown liquid?

When an object is completely submerged under water (LaTeX: \rho_{water}=ρ w a t e r =1000kg/m3,), the buoyancy force on it is 6.2N. If the object is completely submerged under a different liquid (LaTeX: \rho_{liquid}=ρ l i q u i d =781kg/m3,) what would be the buoyancy force on it (in unit of newton)?
