SUMMARY
The density of nitrogen gas at 20°C can be calculated using the ideal gas law, specifically the equation p = m/v, where p is pressure, m is mass, and v is volume. At standard temperature and pressure (STP), one mole of nitrogen gas occupies 22.4 liters. To find the density, the molar mass of nitrogen (approximately 28.02 g/mol) is divided by the volume at STP. The discussion emphasizes the importance of knowing the standard temperature used in calculations.
