At 298K 10 litres of N, at 0.96 alm is added to 32 litres of an evacuvated polythene bag, Subsequently enough O_2 is pumped into the bag at 298K. Now if the total pressure is 0.990 atm, partial pressure of O_2

1.	At 298K 10 litres of N, at 0.96 alm is added to 32 litres of an evacuvated polythene bag, Subsequently enough O_2 is pumped into the bag at 298K. Now if the total pressure is 0.990 atm, partial pressure of O_2
Answer» 0.69 ATM 0.32 atm 0.495 atm 0.5 atm Solution :`P_(N_2)` in `32` lit bag : `P_1V_1 = P_2V_2` `implies P_2 = (10 XX 0.96)/(32) = 0.3` Final PRESSURE = `0.99 ` atm. `implies P_(O_2) = 0.99 - 0.3 = 0.69 atm`.
