Recap - Before It Bursts

Part of the Stoichiometry section of Coddy's Chemistry journey. Lesson 40 of 41.

Challenge

A weather balloon was filled at the ground with $2{,}500\ \mathrm{L}$ of helium at room conditions. Just before it bursts, its volume is $164{,}000\ \mathrm{L}$ and the temperature around it is $220\ \mathrm{K}$ . What is the pressure there? Assume that 1 mol of gas takes 25 L at room conditions, and R = 0.082 atm·L/(mol·K).
