Example Question #5 : Gases
One flask is at STP and another is at . What is the pressure at ?
The pressure of the flask at is .
Because the volume between the flasks and the moles in each flask are constant, we can cancel out and .
At STP, conditions are and .
Example Question #6 : Gases
A 3.00 L container at 273 K is filled with 1.00 mol Cl2(g), which behaves non-ideally.
Using the van der Waals equation, calculate pressure exerted by the gas.
Recall the van der Waals equation for non-ideal gases
Rewrite the equation using the known values and solve for P
