1. The problem statement, all variables and given/known data A gas cylinder contains 4x10^4 cm cubed of hydrogen at a pressure of 2.5x10^7 Pa and a temperature of 290 K. The cylinder is used to foll balloons. Each balloon contains 7.24x10^3 cm cubed of hydrogen at a pressure of 1.85x10^5 and a temp of 290K when full. Find the number of balloons that can be filled from the cylinder. 2. Relevant equations pV=nRT 3. The attempt at a solution I came close. I found the amount in mol in the cylinder to be around 415. I divided this by the amount in mol in one balloon.
