For this method to work the solid must (a) be more dense than the liquid, and (b) not react with nor dissolve in the liquid. Water will be a suitable solvent for determining the volume of metals in this lab. An irregular shaped piece of metal has a mass of 131.0 g. You put it into a 100 mL graduated cylinder containing 22 mL of water, and the water level rises to 68 mL. What is the density of metal in g/ml?
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.
