1.	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 ?
Answer» Solution :First calculate the VOLUME of the cylinder and then WT. of `O_(2)` present at 1 ATM and `75^(@)C` USING PV = n RT
