1. 13.7 NOTES The Ideal Gas Laws

2. A.19 – The Ideal Gas Law
- General relationship derived from other gas laws.

3. PV = nRT
P = pressure (atm)
V = volume (L)
n = number of moles (mol)
R = constant ( atm L/ mol K)
T = temperature (K)
The variables must be the units that are listed above to use that value of R.
Can simplify to Boyle, Charles, and Gay-Lussac if hold appropriate variables constant

4. Example: What volume will 2
Example: What volume will 2.0 mol of hydrogen gas occupy at 40 degrees C and 50 atm?
