17. Boyle’s Law! Lab #52! Volume and Pressure

18. A sample of a gas has a volume of 150 mL when its pressure is 0.947 atm. What will the volume of the gas be at a pressure of 0.987 atm, if the temperature remains constant?

20. You decide to climb to the top of the tallest mountain, Mt. Everest. Before you are about to leave on your epic journey a friend gives you a balloon that was inflated to 800mL at sea level, where the pressure is 760 mmHg. You climb up to the top of Mt. Everest, 29,028ft above sea level, which has an average atmospheric pressure of 221 mmHg. What is the volume of the balloon at the top of Mt. Everest?
