A balloon is filled with a gas. The baloon’s volume is 2.1 L, and the gas pressure is 1.7 atm. Then the balloon is placed in a device squeezing the balloon. The volume of the baloon is now 1.3 L. What is the final pressure of the gas in the balloon? Assume that the temperature and moles of an ideal gas within a balloon are constant. Round your answer to the tenths place.
