(a) A rigid tank contains 1.30 moles of nitrogen, which can be treated as an ideal gas, at a pressure of 27.8 atm. While the tank and gas maintain a constant volume and temperature, a number of moles are removed from the tank, reducing the pressure to 4.30 atm. How many moles are removed? mol (b) What If? In a separate experiment beginning from the same initial conditions, including a temperature T, of 25.0C, half the number of moles found in part (a) are withdrawn while the temperature is allowed to vary and the pressure undergoes the same change from 27.8 atm to 4.30 atm. What is the final temperature (in C) of the gas? C (a) A rigid tank contains 1.30 moles of nitrogen, which can be treated as an ideal gas, at a pressure of 27.8 atm.
