A Cylinder of 20 Litres Capacity Contains a Gas at 100 Atmospheric Pressure. How Many Flasks of 200 Cm3capacity Can Be Filled from It at 1 Atmosphere Pressure, Temperature Remaining Constant? - Chemistry

Numerical

A cylinder of 20 liters capacity contains gas at 100 atmospheric pressure. How many flasks of 200 cm3capacity can be filled from it at 1-atmosphere pressure, temperature remaining constant?

Solution

P = 100 atm
V = 20 litres
P1 = 1 atm
V1 = ?
T = T1

Using equation,

"PV"/"T" = ("P"_1 "V"_1)/"T"_1

(100 xx 20)/"T" = (1 xx "V"_1)/"T"

V1 = 2000 litres = 2 m3 (1000 lit = 1m3)

Volume of one flask = 200/(100xx100xx100) "m"^3

Number of flasks = (2xx1000000)/200 = 10000

Concept: Standard Temperature Pressure (S.T.P.)
