You collected a sample of hydrogen gas in an inverted buret by displacement of water at 23.5 °C. The buret could not be submerged deep enough in the water bath to equalize pressure. The water level in the buret was 9.35 cm above the water level in the water bath. The volume of gas in the buret was determined to be 40.55 ml. a. If the current atmospheric pressure was 29.14 in of Hg, what is the pressure of dry hydrogen in the buret? Show work. b. How many moles of hydrogen are in this sample? Show work.
