You are asked to determine the density of an unknown liquid. You perform the experiment like you did in lab to find the density of water. You prepare a buret with the unknown liquid, then fill it to 0.00 mL. You obtain a dry 50-mL beaker. The mass of the empty beaker is 22.567 g. You go to the buret, and obtain 20.06 mL of the liquid. You then go to the balance, and obtain a mass of 37.125 g. Using the information provided, determine the density of the unknown liquid and report it to the appropriate numbers of significant figures.

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.
