Can I please have help understanding this question? I would really appreciate it. Thanks! A gas cylinder contains 4 x 10^4 cm^3 of hydrogen at a pressure of 2.50 Pa and a temperature of 290K, the cylinder is used to fill balloons. Each balloon when filled contains 7.24 x 10^3 cm^3 of hydrogen at a pressure of 1.85 x 10^5 Pa and a temperature of 290K, calculate the number of balloons that can be filled. (The answer is 741 but I dont understanf the method and concept.)
