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

at constant temperature apply Boyle's law
P1V1 = P2V2
let n number of flask can be filled.
P1 = 100atm
V1 = 2liter = 2*1000cm³ = 2000cm³
P2 = 10atm
V2 = n*200cm³
100*2000 = n*10*200
n = 100
hence 100 flask can be filled.
P1V1 = P2V2
let n number of flask can be filled.
P1 = 100atm
V1 = 2liter = 2*1000cm³ = 2000cm³
P2 = 10atm
V2 = n*200cm³
100*2000 = n*10*200
n = 100
hence 100 flask can be filled.

PV=nRT
since T is constant, PV = constant.
for the cylinder, V₁=2l, P₁=100 atm
when it comes to flask, the pressure becomes 10 atm
let volume becomes x litres.
So P₂ = 10 atm, V₂ = x
P₁V₁ = P₂V₂
⇒100 × 2 = 10 × x
⇒ x = 200/10 = 20 litres
capacity of each flask = 200 cm³ = 200ml = 0.2l
no. of flask that can be filled = 20/0.2 = 100
