Balloons of 2 L capaicty are to be filled with hydrogen, at a pressure of 1 atm and `27^(@)C` temperature, from an 8 L cylinder containing hydrogen at 10 atm, at the same temperature . Calculate the number of balloons that can be filled.

Explanation

To solve the problem of how many balloons can be filled with hydrogen from an 8 L cylinder at 10 atm, we can use the ideal gas law and the concept of moles. Here’s a step-by-step solution:

### Step 1: Calculate the number of moles of hydrogen in the cylinder.
We can use the ideal gas law, which is given by the equation:
\[ PV = nRT \]
Where:
- \( P \) = pressure (in atm)
- \( V \) = volume (in liters)
