An expandable balloon contains 1400L of He at .950atm pressure and 18 degrees Celcius. At an altitude of 22 miles (temperature of 2.0 degrees Celcius and pressure of 4.0 torr), what will be the volume of the balloon?

P*V/T = constant if T is in K

0.95*1400/291 = (4/760)*V/275

V is the final volume, at altitude. Solve fore that.

Note that I had to use the same units for P, V and T on both sides of the equation. 4 torr = 4/760 atm
