उत्तर

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`

Number of flasks = 10000
