4. Freon-12 had been widely used as a refrigerant in air conditioning systems; however, it has been shown to be related to destroying Earth's important ozone layer. What is the molar mass of Freon-12 if 9.27 grams was collected by water displacement, in a 2.00 liter volume at 30.0°C and 764 mmHg. Water's vapor pressure at this temperature is approximately 31.8 mmHg.
The hypothetical compound X has molar mass 67.88 g/mol and vapor pressure of 652 mmHg at 25°C. 50.0 g of coumpound X are introduced in a 15.0 L evacuated flask, sealed and left to rest until the liquid reaches equilibrium with its vapor phase. What will the mass of the liquid be once equilibrium is reached? Insert your answer rounded to 1 decimal digit. Answer: Enter Value g

Departmental Problems for Chapter 5: Gases In the 2015 AFC championship football game, it was alleged that the New England Patriots ber the rules by using underinflated footballs. NFL regulations require footballs to be inflated to between 12.5 and 13.5 psi (psi = pounds per square inch). [Note: this is gauge pressure, not ab- solute pressure.] One football actually used in the game was measured to have a pressure of onl 10.5 psi (gauge). One of the Patriots' coaches later alleged that the explanation was due simply gas behavior: pressure decreases as the temperature decreases. Let's examine that last claim. Suppose that the football remained sealed and nearly rigid (i.e. the volume and moles of gas within the ball did not change). A nearby airport measured the air pressure at game time to be 100.95 kPa. The temperature on the field at the start of the game was 51°F. Suppose that the ball was originally inflated in the locker room to the minimum pressure of 12.5 psi (gauge). In order…
