Calculate the partial pressure of each of the gases in the mixture. Calculate the total pressure of the mixture in atm.
The ideal gas law is derived from empirical relationships among the pressure, the volume, the temperature, and the number of moles of a gas; it can be used to calculate any of the four properties if the other three are known.
The Ideal Gas Law is a single equation which relates the pressure, volume, temperature, and number of moles of an ideal gas. If we substitute in the variable \(R\) for the constant, the equation becomes:
P 1 T 1 = P 2 T 2. This equation is useful for pressure-temperature calculations for a confined gas at constant volume. Note that temperatures must be on the kelvin scale for any gas law calculations (0 on the kelvin scale and the lowest possible temperature is called absolute zero).
Learning Objectives. By the end of this section, you will be able to: Identify the mathematical relationships between the various properties of gases. Use the ideal gas law, and related gas laws, to compute the values of various gas properties under specified conditions.
Learning Objectives. By the end of this section, you will be able to: Define the property of pressure. Define and convert among the units of pressure measurements. Describe the operation of common tools for measuring gas pressure. Calculate pressure from manometer data. The earth’s atmosphere exerts a pressure, as does any other gas.
