A student is asked to make up a 16% sodium chloride solution. She makes the solution by weighing an empty beaker (which has a mass of 98.5g). Sodium chloride is added to the beaker. The mass of the beaker and sodium chloride is 114.71 g. Lastly, the student added 84 mL of distilled water to the beaker. Reweighing the beaker she finds that the mass of the beaker, sodium chloride, ad distilled water is 196.14 g. What is the weight percentage of sodium chloride in this solution? Show all work
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.
