Study Notes
Molar Volume of a Gas
- Molar volume is the number of liters occupied by one mole of a gas.
- The molar volume of an ideal gas depends on temperature and pressure.
- At a fixed temperature and pressure, Boyle's Law can be used to describe the relationship between pressure and volume.
- Boyle's Law states: $PV = constant$ or $P_1V_1 = P_2V_2$
- Avogadro's Law states that the molar volume of any gas at STP (273 K and 1 atm) is 22.4 L/mol.
- Partial pressure is the pressure exerted by a single gas in a mixture.
- The total pressure of a mixture is the sum of the partial pressures of each gas: $P_{total} = P_1 + P_2 + ...$
- This phenomenon is known as Dalton's Law of Partial Pressures.
Gas Mixtures
- A gaseous mixture is created when a gas comes into contact with water and gets saturated with water vapor.
- The partial pressure of water vapor can be found using Table 1, which shows the relationship between temperature and partial pressure of water vapor.
