Use the References to access important values if needed for this question. A general chemistry student found a chunk of metal in the basement of a friend's house. To figure out what it was, he used the ideas just developed in class about density. First he measured the mass of the metal to be 311.2 grams. Then he dropped the metal into a measuring cup and found that it displaced 15.9 mL of water. Calculate the density of the metal.

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.
