Initially bulb "a" contained oxygen gas at `27^(@)C` and 950 mm of Hg and bulb "B" contained neon gas at `27^(@)C` and 900 mm of Hg. These bulbs are connected by a narrow tube of negligible volume equipped with a stopcock and gases were allowed to mix-up freely. The pressure obtained in the combined system was found to be 910 mm of Hg.
If volume of bulb B was measured to be 10 L, then find the volume of oxygen gas present initially in bulb "A" .
