Lesson 17

Ideal Gas Law

• Relates temperature, pressure, volume, and number of moles of particles
• Formula: PV=nRT
• R is the constant and R = 0.082 • atm/mol • K
• R is the same for all gases
• R can change with different units like changing Liters to Milliliters

To find the total number of molecules in a sample of gas, take the number of moles and multiply by (6.022 • 10^23)

Practice Problems

1) the ideal gas law is: pressure x volume = number of molecules or moles x the constant 0.082 x temperature

 

2)
