4. You collect a sample of hydrogen gas in an inverted buret by displacement of water at 230 °C. The buret could not be submerged deep enough in the water bath to equilize pressure. The water level in the buret was 14.65 cm above the water level in the water bath. The volume of gas in the buret was determined to be 32.60 mL. a. If the current atmospheric pressure was 29.45" of Hg,...
