- Homework Statement
- A gas cylinder contains 4.00x10^4 cm^3 of hydrogen at a pressure of 2.50x10^7 Pa and a temperature of 290 K. The cylinder is to be used to fill balloons. Each balloon, when filled, contains 7.24x10^3 cm^3 of hydrogen at a pressure of 1.85x10^5 Pa and a temperature of 290 K.
Calculate the number of balloons that can be filled.
Below is the solution but I can't seem to understand it.
- Relevant Equations
- PV=nRT, P1V1=P2V2
P1V1=P2V2
(2.5x10^7x4x10^4)/1.85x10^5 , V2 = 5.41x10^6 cm^3
5.41x10^6=4x10^4+7.24x10^3 N
N= 741
(2.5x10^7x4x10^4)/1.85x10^5 , V2 = 5.41x10^6 cm^3
5.41x10^6=4x10^4+7.24x10^3 N
N= 741
