An object is put into a graduated cylinder with 50.0 mL of water. The two together take up a volume of 65.0 mL. The object weighs 200.0 g. Given the densities of the objects below, what was the identity of that object?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.

We need to calculate the density using the given data and then compare it with given density of all metals.
