Help please. A balloon originally had a volume of 4.39 L at 44 degrees Celsius and a pressure of 729 torr. The balloon must be cooled to ________ degree Celsius to reduce its volume to 3.78 L (at constant pressure)

Question

Use PV=nRT to calculate how many moles you have. Then use that number of moles and the same pressure with the new volume to calculate the new temp. Make sure your units match the value of R you choose.
