Study Notes
Avogadro's Constant
- Avogadro's constant is 6.022 x 10^23
- This constant represents the number of particles (atoms, molecules, ions, etc.) in one mole of any substance
Molar Volume
- At standard temperature and pressure (STP), 1 mole of any gas takes up 22.4 liters of space
Avogadro's Law
- Avogadro's law states that the volume of a gas is directly proportional to the number of moles of gas at constant temperature and pressure
- The equation representing Avogadro's law is V/n = k, where V is volume, n is the number of moles, and k is a constant
- If the number of moles is doubled, the volume of the gas will also double
Applying Avogadro's Law
- Avogadro's law can be used to solve problems involving molar volume
- For example, to find the volume of a gas given the number of moles, you can use the equation V = n x 22.4 L/mol
Gas Behavior
- The particles of a gas move randomly and collide with the inside of a container
- When a gas is inflated into a container, the particles collide with the walls of the container, causing it to expand
- The pressure of a gas is caused by the force exerted by the gas particles on the walls of the container
Air Composition
- The main components of the breath we inhale and exhale are nitrogen, oxygen, carbon dioxide, and water vapor
