A stock solution is made by dissolving 1/4 c sugar into 2.5 c water. The total volume of the stock solution is 2 2/3 c. For these calculations, assume one cup (1 c) is equal to 236 mL. Four dilutions are prepared from the stock solution according to the recipes below. Dilution 1: 1/4 c stock solution diluted to 2.5 c Dilution 2: 1/3 c stock solution diluted to 2.5 c Dilution 3: 1/2 c stock solution diluted to 2.5 c Dilution 4: 2/3 c stock solution diluted to 2.5 c • • • Use the dilution equation to calculate the concentration of Dilutions 1-4. Write your answers within the table below. Show your calculations within the space provided.
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.
