1.) What is the total pressure, in millimeters of mercury, of a gas mixture containing argon gas at 0.25 atm, helium gas at 350 mmHg, and nitrogen gas at 360 Torr?
2.) Your spaceship has docked at a space station above Mars. The temperature inside the space station is a carefully controlled 24 degrees Celsius at a pressure of 745 mmHg. A balloon with a volume of 425 mL drifts into the airlock where the temperature is -95 degrees Celsius and the pressure is 0.115 atm. What is the final volume, in millimeters, of the balloon if n does not change and the balloon is very elastic?
