4 gram oxygen and 2 gram hydrogen are kept in a one-litre container at `0^(@)C`. Calculate the total pressure.

Explanation

To solve the problem of calculating the total pressure of 4 grams of oxygen and 2 grams of hydrogen in a one-litre container at 0°C, we will use the ideal gas equation, which is given by:

\[ PV = nRT \]

Where:
- \( P \) = pressure (in atmospheres)
- \( V \) = volume (in liters)
- \( n \) = number of moles of the gas
