Problem
A sealed glass bulb of volume 2.50L contains dry nitrogen gas at 1.013×105Pa and 300K.
(a) Calculate the number of moles of nitrogen present in the bulb.
(b) Determine the total number of nitrogen molecules in the bulb.
(c) The bulb is now thoroughly evacuated and the same number of nitrogen molecules are introduced but the temperature is maintained at 400K while the pressure is kept the same. What will be the new volume required to accommodate these molecules?
