A scuba tank, when fully charged, has a pressure of 195 atm at 20oC. The volume of the tank is 11.3L. (a) What would the volume of the air be at 1.00 atm and at the same temperature? (b) Before entering the water, a person consumes 2.0L of air in each breath, and breathes 12 times a minute. At this rate, how long would the tank last?
