Consider the adjacent diagram to answer these questions :
Initially, flask A contained oxygen gas at 27ºC and 950 mm of Hg, and flask B contained neon gas at 27ºC and 900 mm. Finally, the two flasks were joined by means of a narrow tube of negligible volume equipped with a stopcork and gases were allowed to mixup freely. The final pressure in the combined system was found to be 910 mm of Hg.
If volume of flask B was measured to be 10L, mass of oxygen gas present initially in flask A was
- 2.00 g
- 4.00 g
- 8.00 g
- 16.00 g
Answer
(B) 4.00 g
