You are performing an experiment in lab that is sensitive to the density of nitrogen in the air. If the density of nitrogen is greater than 1.00g/L you must bag your experiment and hope for better conditions tomorrow. The barometer in the lab has a 626mm column of mercury and the thermometer reads 26degrees celsius. Given that air is 78% by volume nitrogen, what is the density of nitrogen in the lab? Can you do your experiment or should you just go home?
