A chemist makes 640.mL of mercury(II) iodide HgI2 working solution by adding distilled water to 60.0mL of a 6.66μmolL stock solution of mercury(II) iodide in water. Calculate the concentration of the chemist's working solution. Round your answer to 3 significant digits.
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.

When a solution of Molarity M1 and volume V1 is diluted by adding water to a final volume V2 and molarity M2 , then
M1V1 = M2V2
This is called dilution formula
