Pressure in a bulb dropped from 2000 to 1500 mm in 50 minuite when the contained oxygen leaked through a small hole. The bulb was then completely evacuated.A mixture of oxygen and another gas of molecular weight 72 in molar ratio `1:1` at a total pressure of 6000 mm was introduced. Find the molar ratio of two gases remaining in the bulb after a period of 70 minute. If your answer is `x` then fill your OMR with `46 x` (Exclude decimal places)
