Liquid nitrogen has a density of 0.808 g/mL and boils at 77K. Researchers often purchase liquid nitrogen in insulated 175 L tanks. The liquid vaporizes quickly to gaseous nitrogen, which has a density of 1.15g/L at room temperature and atmospheric pressure, when the liquid is removed from the tank. Suppose that all 175 L of liquid is removed from the tank. Suppose that all 175L of liquid nitrogen in tank accidentally vaporized in a lab that measured 10.00m x 10.00 m x 2.50 m. What maximum fraction of the air in the room could be displaced by gaseous nitrogen?
