A weather balloon is filled with 0.295 m^3 of helium on the ground at 18 degrees Celsius and 756 torr. What will the volume of the balloon be at an altitude of 10 km where the temperature is -48 degrees Celsius and the pressure is 0.14 atm?

ok this is what ive done so far:

V1=.295 m^3

T1=18+273=291 K

P1=756 x 1/760 = .9957 atm

P2=.14 atm

What do I do next?

All I know is P1V1/n1T1 = P2V2/n2T2

(.295 * .9957)/291 = (.14 * V)/225

Solve for V.

Sorry i dont have my calculator right now ><
