Question

A gas cylinder having a capacity of 20 litres contains a gas at 100 atmos. How many flasks of 200 cm3 ca- pacity can be filled from it at 1 atmos. pressure if the temperature remains constant? [10,000]​

Answer 1

Let n numbers of flask required  

20liters = 20000cm³

apply boyel's law

P1V1 == P2V2

P1 = 100 atm  

V1 = 20000cm³

P2 = 1 atm

V2 = n*200cm³

100*20000 = 1*n*200

n = 10000
