You collect a sample of hydrogen gas in an inverted buret by displacement of water at 22.0 °C.  The buret could not be submerged deep enough in the water bath to equilize pressure.  The water level in the buret was 14.43 cm above the water level in the water bath.  The volume of gas in the buret was determined to be 32.60 mL.  If the current atmospheric pressure was 29.45" of Hg, what is the pressure (torr) of dry hydrogen in the buret? How many moles of hydrogen are in this sample?

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
