You decide to climb to the tops of some of the tallest mountains. Before you are about to leave on your epic journey, a friend gives you a balloon with a volume of 800.0 ml that was inflated under standard atmospheric pressure (760mmHg). You climbed two different mountains with this balloon: Mt. Everest 29,028 ft above sea level which has an average atmospheric pressure of 221 mmHg, and Mt. McKinley 20,320 ft above sea level which has an average atmospheric pressure of 345 mmHg. Before calculating any values predict on which mountain the balloon will have the largest volume. What was the size of the balloon on each mountain top? (show your calculation)

Iknow the answer is a but i don't know why
