One litre of oxygen at a pressure of \(1 \mathrm{~atm}\) and two litres of nitrogen at a pressure of \(0.5 \mathrm{~atm}\), are introduced into a vessel of volume \(1 \mathrm{~L}\). If there is no change in temperature, the final pressure of the mixture of gas (in atm) is
- A \(1.5\)
- B \(2.5\)
- C \(2\)
- D \(4\)
Answer & Solution
Correct Answer
(C) \(2\)
Step-by-step Solution
Detailed explanation
Ideal gas equation is given by \[ p V=n R T \] For oxygen, \(p=1 \mathrm{~atm}, V=1 \mathrm{~L}, n=n_{\mathrm{O}}\) Therefore Eq. (i) becomes…
