A mixture of Na2SO4 and its hydrate Na2SO4•10H2O has a mass of 1.5099 g. After heating to drive off all the water, the mass is only 1.1410 g. What is the weight percentage of Na2SO4•10H2O in the original mixture? Report your answer to 4 significant figures. Molar masses: Na2SO4 142.04 g/mol; Na2SO4•10H2O 322.19 g/mol.
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.
