A cylinder of 20 litres capacity contains a gas at 100 atmospheric pressure. How many flasks of `200 "cm"^3` capacity can be filled from it at 1 atmosphere pressure , temperature remaining constant ?

Explanation

To solve the problem, we can use the ideal gas law, which states that for a given amount of gas at constant temperature, the product of pressure and volume is constant. This can be expressed as:

\[ P_1 V_1 = P_2 V_2 \]

Where:
- \( P_1 \) = initial pressure (100 atm)
- \( V_1 \) = initial volume (20 liters)
- \( P_2 \) = final pressure (1 atm)
