Problem: A weather balloon is filled with helium to a volume of 1.61 L at 734 torr. What is the volume of the balloon after it has been released and its pressure has dropped to 0.844 atm? Assume that the temperature remains constant.

FREE Expert Solution

A weather balloon is filled with helium to a volume of 1.61 L at 734 torr. 

We’re being asked to determine the volume of the gas sample after it has been released and its pressure has dropped to 0.844 atm


Recall that the ideal gas law is:


PV=nRT


The pressure and volume of a gas are related to the number of moles, gas constant and temperatureThe value nRT is constant
