Archimedes Principle and Equilibrium Applied to an Object

An object is suspended from the bottom end of a spring. With the object in air, the spring exerts upward force Wa= 30 nt. With the object immersed in water, the spring exerts upward force Ww= 20 nt. With the object immersed in Liquid X, the spring exerts upward force Wx= 24 nt.
see ATTACHMENT for a diagram.
Find the density of Liquid X.
