A student carried out a similar experiment to the one in this lab, but used a hydrate of cobalt (II) chloride, CoCl2 n H20, in an attempt to find the value of n. The student used 5.125 grams of the hydrate and after the second and final heating, the anhydrous formed weighed 2.797 grams. What is the % error based on these experimental results? Round the experimental value of n to the nearest whole number and use it as the known value. Assume the known value of n to be an exact number. Enter the number only with the proper number of significant figures. Do not use scientific notation.

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.
