The vapor pressure of a volatile liquid can be determinedby slowly bubbling a known volume of gas through it at aknown temperature and pressure. In an experiment, 5.00L of N2 gas is passed through 7.2146 g of liquid benzene(C6H6) at 26.0 °C. The liquid remaining after the experimentweighs 5.1493 g. Assuming that the gas becomes saturatedwith benzene vapor and that the total gas volume andtemperature remain constant, what is the vapor pressure ofthe benzene in torr?
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.
