The Ideal Gas Law is a fundamental equation in the field of thermodynamics that relates the pressure, volume, and temperature of a gas. The equation is represented as: PV = nRT, where P is the pressure, V is the volume, n is the number of moles of gas, R is the gas constant, and T is the temperature in Kelvin.
When solving problems using the Ideal Gas Law, it is important to remember to convert all units to the appropriate form, such as converting temperatures to Kelvin and pressures to atmospheres. By applying the Ideal Gas Law, one can calculate unknown variables such as pressure, volume, temperature, or the number of moles of gas.

Worksheet Answers
1. A gas occupies a volume of 3.50 L at a pressure of 0.800 atm and a temperature of 300 K. How many moles of gas are present?
Answer: n = PV / RT = (0.800 atm)(3.50 L) / (0.0821 L atm/mol K)(300 K) = 0.143 moles
Practice Problems
2. A gas has a pressure of 2.00 atm, a volume of 5.00 L, and a temperature of 400 K. What is the number of moles of gas present?
Answer: n = PV / RT = (2.00 atm)(5.00 L) / (0.0821 L atm/mol K)(400 K) = 0.122 moles
