Step 1
We can use Archimedes' principle, which states that the buoyant force on an object is equal to the weight of the fluid displaced by the object. In this case, the buoyant force is the difference between the weight of the object in air and the weight in alcohol, Show more…

An object hangs from a spring balance. The balance registers 30 $\mathrm{N}$ in air, 20 $\mathrm{N}$ when this object is immersed in water, and 24 $\mathrm{N}$ when the object is immersed in another liquid of unknown density. What is the density of that other liquid?
