A gas cylinder contains 370 g of `O_(2)` at 30 atm and `25^(@)C`. What mass of `O_(2)` would escape if first the cylinder were heated to `75^(@)C` and then the valve were held open until the gas pressure was 1 atm, the temperature being maintained at `75^(@)C` ?

Text Solution

Verified by Experts

The correct Answer is:
359 g
First calculate the volume of the cylinder and then wt. of `O_(2)` present at 1 atm and `75^(@)C` using pV = n RT
