A cylinder of 20litres capacity contains a gas at atmospheric pressure. How many flasks of 200 cm^3 capacity can be filled with it at 1 atmospheric pressure , temperature remains constant. No copy or spam is allowed!!

It is stated that,
The temperature is constant so, It can be done by using Boyle's.
For case one,
Pressure(P₁) = 760 mm Hg
Volume(V₁) = 20 litres
For case two,
Pressure(P₂) = 1 mm Hg
Volume(V₂) = V₂
We know that,
P₁V₁ = P₂V₂
⇒ 760×20 = 1×V₂
⇒ V₂ = 1520 litres
So, at the next time the volume of the gas becomes 1520 litres
The capacity of each flasks_
200 cm³
= 200/(10×10×10) dm³
= 0.2 dm³
= 0.2 litres
So, the number of flasks is required to contain the gas _
(1520÷0.2)
= ( 15200 ÷ 2)
= 7600 flasks
∴ 7600 flasks are required to contain the gas.
Answer:
Pressure(P₁) = 760 mm Hg
Volume(V₁) = 20 litres
ii)
Pressure(P₂) = 1 mm Hg
Volume(V₂) = V₂
We know that,
P₁V₁ = P₂V₂
⇒ 760×20 = 1×V₂
⇒ V₂ = 1520 litres
So, at the next time the volume of the gas becomes 1520 litres
The capacity of each flasks_
200 cm³
= 200/(10×10×10) dm³
= 0.2 litres
So, the number of flasks is required to contain the gas _
(1520÷0.2)
= ( 15200 ÷ 2)
= 7600 flasks
