Please let me know how you would approach the gas law problem. Here goes:
If the pressure exerted on the gas in a weather ballon decreases from 1.01 atm to 0.562 atm as it rises. By what factor will the volume of the gas in the ballon increase as it rises?
I can't seem to figure out which gas law mathematical equation to apply.
Thanks for being helpful.

It's just P and V; therefore,
P1V1 = P2V2 and you want to solve for V1/V2
