Question

2 litres flask contains 0.2 moles of moist N, gas at
300K at 3 atm. If this moist gas is shifted to one
litre flask, then the pressure exerted in the new
flask is
(1) 4.92 atm
(2) 5.46 atm
(3) 6 atm
(4) 3.87 atm​

Answer 1

According to the Boyle's Law for same amount of gas pressure is inversely proportional to volume at constant temperature .

P1 V1 = P2 V2

3 x 2 = P2 x 1

P2 =6atm
