Recap - Balloon High Up

Part of the Stoichiometry section of Coddy's Chemistry journey. Lesson 39 of 41.

Challenge

A weather balloon holds 100 mol of helium. As it rises the air thins and the balloon swells. At a height of about 28 km the pressure is $0.015\ \mathrm{atm}$ and the temperature is $225\ \mathrm{K}$ . Calculate the volume, $V$ , of the helium in the balloon there. Use R = 0.082 atm·L/(mol·K).

Try it yourself

Solve for $V$
