Posted by Amy on Wednesday, January 23, 2013 at 6:19pm.

A student collected H2 gas in a buret by displacing water at 22.0 C. The buret could not be submerged deep enough in a water bath to equalize the pressure. The water level in the buret was 18.2 cm above the water level in the water bath. The volume of the gas in the buret was determined to be 38.6 mL.

a) If the atmosphere pressure was 748 torr, what is the pressure of the Hydrogen in the buret? (Density of Hg is 13.6 g/mL)

b) How many moles of Hydrogen did the student collect?
