the cylinder of 20 liters capacity contains gas at atmospheric pressure. How many flasks of 200 cm3 capacity can be filled from it at 1 atmosphere pressure, temperature remaining constant ?
P= 100 atm
V= 20 ltrs
P1 = 1atm
V1=?
T= T1
Using equation
PV/T = P1V1/T1
100 x 20/T = 1 x V1/T
V1= 2000 ltrs = 2m3 ( 100 lit = 1m3)
Volume of one falsk = 200/100x100x100
Number of flasks = 2 x 1000000/200 = 10000
