1. A 22.65-g sample of a solid is placed in a flask. Ethanol is added to the same flask having the total volume together of 45.00 mL. The solid and ethanol together weigh 38.58 g. At room temperature, the density of ethanol is 0.789 g/mL. What is the density of the solid? Report your answer in correct significant figures with proper units
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.
