The density of nitrogen prepared in the laboratory is less than that collected from air because laboratory-prepared nitrogen is often in a gaseous state, while nitrogen collected from air may contain impurities or be in a mixture with other gases which affects its density. Additionally, laboratory-prepared nitrogen may be at a higher temperature compared to ambient air, causing it to have a lower density.
