Reference no: EM13910485

An oxygen enriched air, which contains at least 50% by volume pure oxygen, has been sold by a company. To test their claim, a 1000 mL glass bulb was filled with the gas to a total pressure of 750 mm Hg at 68°F. The weight of the gas sample was found to be 1.236 g. What is the exact volume percent of oxygen gas in the mixture?
