A gas cylinder having a capacity of 2 litre contains a gas at 100 atm. How many flasks of 200 cm3 capacity can be filled from it at 10 ATM pressure, if the temperature remains constant

A gas cylinder having a capacity of 2 litre contains a gas at 100 atm.

1.	A gas cylinder having a capacity of 2 litre contains a gas at 100 atm. How many flasks of 200 cm3 capacity can be filled from it at 10 ATM pressure, if the temperature remains constant
Answer» At constant temperature apply BOYLE's law P1V1 = P2V2 let n number of FLASK can be FILLED. P1 = 100atm V1 = 2liter = 21000cm³ = 2000cm³ P2 = 10atm V2 = n200cm³ 1002000 = n10*200 n = 100 hence 100 flask can be filled.
