Question

At room temperature, helium gas is present in a 5 L cylinder at 10 atm pressure. How many balloons having a maximum inflation volume of 200 cc at 0.1 atm limiting pressure, can be filled using helium gas in the cylinder at its maximum inflation and room temperature?

Answer 1

2475 balloons can be filled.

Explanation:

Given that,

P1 = 10 atm

V1 = 5 L

P2 = 0.1 atm

V2 = 200 cc or 0.2 L

Using Boyle's law,

P1 * V1 = (P2 * V2)                      (T is constant)

Let n be the number of ballons filled

P1 * V1 = n(P2 * V2)        

⇒ 10 * 5 = 0.1 * 0.2

⇒ 50/0.02 = n

∵ n = 2500

Thus, option D is the correct answer.
