Given:
A vessel of volume 16.6 litres containing an ideal gas at 47°C and pressure 150 kPa is allowed to leak till the pressure falls to 102 kPa at the same temperature.
To find:
Moles of gas leaked ?
Calculation:
Let's calculate the initial moles:
We know that for an IDEAL GAS :
- As per the question, the temperature remains constant. Since the vessel volume will always remain same, V becomes constant.
So, number of moles lost
So, number of moles leaked is 277.9 moles.
