A weather balloon is inflated to a volume of 27.4L at a pressure of 735mmHg and a temperature of 29.1∘C. The balloon rises in the atmosphere to an altitude where the pressure is 360.mmHg and the temperature is -13.9∘C.
Assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.

Since you are using 5 of the variables, you should use the combined gas law in order to calculate for V2.

its saying in my book its under section that has ideal gas law 
PV=nRT

kaibaseto · Answer

If it was the ideal gas law, then the question would either ask you for the number of mols or to calculate the number of mols. Also, the ideal gas law does not allow for calculating changes in the volume. In this case, V2.
